Did you have a previous version of digital file pro installed? I think the HelperUploadVB.asp that is on your server must be from a previous version of DFP, line 602 of that file from version 1.1.3 is:
ExitLoop = false
The error occurring on that code does not make any sense.
try deleting the WA_DigitalFilePro in your Dreamweaver site, and also from the server. Then edit the DFP instance on your page to recreate it.
If you get the error again, copy the error including line number into your post and send a copy of the HelperUploadVB.asp from your site.
