Upgraded to Sage ACCPAC version 6.0 last October and it has been running fine.  Last Thursday, the logon manager appears in the far upper left hand corner of the screen.  After I enter user name and password, I can't access any functions.  The signon manager appears in the system tray and the ACCPAC icon appears active.  I have to right click and exit to close out of ACCPAC.  So I uninstalled and reinstalled all to no avail.  There are no error messages.

Any ideas?
