Crystal Reports 8.5 on XP

Can someone please help? I just installed CR 8.5 and installed the last service packs and hotfixes. When I click on the save button I get an error message that says: The handle is invalid. Also, when I use the export button I get an error message saying that there was an error creating the tempory file. I have domain admin rights, which shouldn’t matter because I am trying to create the temp file locally. I am an administrator on my local machine as well.

Any suggestions?

Thanks!!
