You may be missing a file here or one is outdated. Please go to your client area and download a full set of files then upload the contents of "ips_****" folder to your server, overwriting what is there. 

I still get the error after. I have not receive anymore reply from ips support

This should be fixed with Beta 2. Certain unexpected content in the deletion log database table can trigger this error (and similar errors of class not found during the upgrade) which we have a patch in testing for. Thank you for testing the beta!
