Multi file upload not working

[bignslow]

I can't get Multi file upload working on my site. Single file upload works fine. There is no specific error message displayed. No matter how many files I try I get this error message.

I just uploaded 4 files with the flash-driven uploader to your gallery successfully.

Did you have to do anything special? I can't get it to with on either Firefox or IE9. Perhaps it has something to do with the version of Flash installed on the PC?

That's strange. I tried my work computer and it works. I guess it's my computer then.
