First of all, I going to assume you mean upgraded from 8.0.0 to 8.0.2. Secondly, to fix your problem, search your computer for the SSI_Data.settings file and rename the extension to .xml. Then try to enter the upload dialog. If it succeeds, then open the SSI_Data.xml file and you should be able to copy the settings back in. Sounds like something in the conversion didn't go right.
