When uploading files, the Request.Form object is no longer allowed, if you are using Digital File pro, it will create a WA_DFP_UploadObj.Form collection to use in stead.
any where that uses the Request.Form collection, will need to be edited to use the WA_DFP_UploadObj.Form collection instead.
change line 100:
if (cStr(Request.Form("Submit")) <> "") then
to:
if (cStr(WA_DFP_UploadObj.Form("Submit")) <> "") then
