Are you adding it from the My Snipes tab itself?
There does seem to be a problem that came up with AOL starting yesterday. We're not sure why but if it's something we did we'll fix it.
For now there is an easy solution:
#1 use Internet Explorer outside of AOL. Do not use AOL's web browser.
#2 If #1 doesnt work then use any other web browser, Mozilla, Firefox, Netscape, Opera, etc.
#3 file a support case on our help tab.
