Can't get Missing Sync to work!

[tell_sackett]

Okay, so I dropped $40 to be able to sync my 8700 to my Mac. Now the application (Missing Sync for Blackberry v2.0.2) won't start on my Blackberry. I get the following error:
Error Starting
MissingSync Class
'javax.microedition.io.file.File
SystemListener' not
Found

I've re-installed once, changed the security settings to 'Allow' (per the Mark/Space tech support database) and restarted multiple times. Any other thoughts?

I was about to get this but I think I found your problem. Under Blackberry requirements it says you have to have a Data plan or SD card. I don't have either so I'm SOL. Do you have one of the two?
