file_column problem

Hey Everyone-

I would really appreciate some help with the use of the file_column plugin. I have it working very well on my local Windows development machine, but have not been able to get it to work on my shared host (dreamhost). When trying to upload a file, I get this error message:

"Application error Rails application failed to start properly"

The thing is, file_column is _mostly_ working: it accepts the uploaded file, saves it to the local file system and updates the database with the filename. There is some last step in the file upload process within file_column that is generating this error message.

Has any one seen this before? I thought it may have something to do with file permissions on the shared host which don't exist on my Windows development machine. Other than that, I'm at a loss.

Thanks for any help or advice!
