I've downloaded a few rings off this site and i transfered them to my pc then to my phone but when i try to setup my ringtone. none of them show up or cant even use as a ringtone...? could anyone help me on this?
thanks

Update:
i just looked at the ringtone i bought off the web. the file says fl.file? so i'm guessin that i need to convert the ringtones i downloaded from here to a fl.file in order to work?

you service provider could have blocked your phone from using an MP3 as a ringtone unless you download it from them here a work around
Step 1.

Download and install the Sony Ericsson Digital Rights Management Packager
Windows : My Account
Mac: My Account

Step 2.

Select a mp3 you would like to protect (use as a ringtone).

Step 3.

Run DRM Packager
Start->Programs-> Sony Ericsson-> DRM Packager-> DRM Packager
Go to File, add files and select the mp3 you would like to use.

Step 4. (Configuration)

Go to Options -> Configuration -> and select combined delivery and also uncheck
“ Place rights in separate folder” and click the little box with the … on it and place where you want them to go (ex. My Documents/My Music folder) click OK
A window will pop up saying “Before proceeding with the combined delivery…. “
Click OK. Use the following info to fill in the blanks.
Content ID: myCellPhone @ Blah.com
Enable right = checked
Check Start time checked and date set to (which ever today’s date is)
Check End time checked and date set to (which ever today’s date is but year 2015)
click OK

Step 5 Creating the dm file(s)

Click on your MP3 file to highlight it
Click on Create DRM content
Now you can send this file to your device , you will be able to set this mp3 as a ringtone.

Adding new file to your phone

1. Plug in your W580i or other cell phone. IMPORTANT: Choose Phone Mode
2. Go to START – ALL PROGRAMS – SONY ERICSSON – SONY ERICSSON PC SUITE. (you need the version 3.107 for it to work with the w580i)
3. Then go to your little phone icon by your clock (bottom right corner)
4. Right click on phone icon and scroll up to File Manager and click on it
5. MyPhoneExplorer. Will open, click on “Your phone” icon so Memory Stick and Phone Memory folders show.
6. Minimize that window so it takes up only half your screen. Then pull up the folder you put the “adjusted” MP3 file you wanted to use as a ringtone. Minimize that too to half the screen so you can see that window AND the MyPhoneExplorer window at the same time. High light the .DM file you made out of your MP3 and drag it to the MyPhoneExplorer and put it under the Memory Stick folder and the Phone Memory folder.
7. IMPORTANT: Do not go into memory stick or phone memory. It will take a bit of time to transfer. Check your phone. It will have a pop up saying you have transferred a music file, click yes to install it into the Music folder.
After that another pop up will come up asking you how to use it. In the list of options, choose "Ring tone" and you are done!

"Sony Ericsson Digital Rights Management Packager" i cant find that any where? i googled it but nothin comes up :/

You can find in Sony Ericsson Miscellaneous Docs & Tools

SE DRM and other tools

I tried what you stated and its not working. When I first tried it gave me an error saying "cannot move file" or somethign along those lines.
So I uninstalled the Sony Ericsson PC Suit and reinstalled it and now no folders (memory stick and phone memory) are showing up under "My Phone".

I have no clue on what to do now...

If I take ringtones off the site and put them through the program, does anyone know if it'll cost me anything?
