Can't import AIFF to iTunes! What to do?

Trying to study for exams and recorded stuff to listen to on my iPod. File created in Audacity as an .aiff file.
In the past, I've dragged this directly to the iTunes Library icon and it worked. Today, no. Haven't done anything to change computer or iTunes settings lately. Prefs(Imports)=Apple Loseless Encoder/Automatic.
I get the (+) sign as if it were going into the library but can't find the file by title. Can't open it if I use "Open with.." iTunes from its desktop location either.
So, I created a new folder in the iTunes library and drug the file into it. I can see the folder and the file. If I "get Info" I can pre"view" my file and hear the text. But I can't get it to open through iTunes.

To see if this was a global problem, I tried downloading a songfile (.mp3) and opened it from the desktop into iTunes without a hitch. So iTunes will accept stuff, just not this.

Any suggestions? I sorta need this to study with. Sorta desperately.
TIA

Hmm... Audacity doesn't export to AIFF unless you have an insider copy of it...

You can save as a .aup project, .mp3, .wav, or .ogg... but not aiff, so that's probably a good place to start with diagnosis.

Don't have an insider copy.
Downloaded Audacity from SourceForge some weeks ago. File options listed are: export to AIFF, MP3, OGG. Wav not listed.
When trying to do mp3 audacity looks for some file I can't find.
Don't know about ogg.....

Still no go

Tried that. Didn't work.

Audicity definitely exports to AIFF, and they normally import into iTunes fine... Does your Audicity Preferences window look like this?

As there are 3 types of AIFF and 5 of WAV, some of the types of WAV wouldn't play on a PC so maybe some types of AIFF don't play on a Mac... Make sure the top one is selected.

Thanks for the suggestion! I'll check it out tonight at home. Hope it works!
