Recording for Rhinospike

Hello, I have just recorded my first Italian text for another Rhinospike user.
I recorded I with Audacity and saved is as I save my recordings for lingq. However, when I upload it, I always get this message:
“Uploaded file was rejected because it is not a valid MP3 file.”
The mp3 file does open in iTunes and I can listen to it without any problems. I tried changing some settings, but the result is always the same. What am I doing wrong?

I have no idea Michele, but I hope you put in a plug for your language content at LingQ when you do them.

Michele,

Can you email me one of the files that is causing you trouble? I’ll see if I can figure out what the issue might be.

I have no idea Michele, but I hope you put in a plug for your language content at LingQ when you do them.

Steve, I forgot to mention LingQ in the only text I have recorded. Should I mention it at the end of the recording, in a comment, or just on my profile?

Alex, I will send you the only file I have recorded for Rhinospike. Thanks in advance.
