I worked on a return 2 days ago with no problems whatsoever.  All that's needed is to run final review and efile.  I come back today to complete the return and Pro Series 19 wont open at all!  When I try to open, it starts to buffer for a few minutes then the program closes.  I tried to open the back up copy of the return from my external hard drive and nothing works.  Eventually I tried to troubleshoot and got the following message:  An error has occurred attempting to launch ProSeries Update.  Error Code 5.

Like I said, everything worked fine until yesterday.  Has anyone had this problem?
