Before you clicked import, what was the format of the WAV file? It should display it in the list. Unfortunately despite the fact WAV files all have the same extension, there's hundreds of different kinds, and the OGG converter only supports certain kinds. Anything which says "PCM" ought to work though.
Resurrecting an old thread, but I figured it may be better than opening a new one. :)
I have run into the same problem. The source WAV file's details are "PCM - mono - 16-bit - 8000 Hz". It fails to convert to OGG. I can send the file per PM if it's a bug and not a case of me missing the obvious (quite likely, it's just my third day with C2!).
(edit: I PM'd you the file, Ashely. Saves a step if it's a bug.)Mivo2012-03-08 01:56:20
@Mivo: Why not just use a tool that specializes in converting sound files? Audacity it's a great free software that I use to convert sound files to import into C2 without a hitch. VampyricalCurse2012-03-08 02:54:37
