Why wont my downloaded ringtones be ringtones

[newportpaco]

I have used audiko to get my ringtones many times but I got a new computer and now when I try to add them add them as a ringtone they just go to my library and not to my ringtone section. Any ideas how to fix this.

check the length of the ringtone. they must be 0:30 or less

Some of the ringtones I downloaded were ones that I used from the same site before I had to erase them because of the new computer. Thats what I dont understand.
