HELLO,
You will need to post some details regarding this problem:
1. Please post the contents of event log corresponding to the date and time (if you remember this) when the program was unexpectedly shut down. Follow steps below:
a. Click Start, and then click Control Panel. Click Performance and Maintenance, then click Administrative Tools, and then double-click Computer Management. Or, open the MMC containing the Event Viewer snap-in.
b. In the console tree, expand Event Viewer, and then click the log that contains the event that you want to view.
c. In the details pane, double-click the event that you want to view.
The Event Properties dialog box containing header information and a description of the event is displayed.
2. Also, have you tried restarting the program. Had it again shutdown unexpectedly?
3. Also as Stang02GT had asked:
Do you know of any new software that could have been installed on that machine? Something could have been installed that is clashing with your program.
Post back with details.
Viruses often causes such things to happen. Try running full anti-virus scan on your PC
I am reminded of a practical (yes it's practical) saying:
"In God we trust, all others we virus scan" :)
HOPE THIS HELPS.......
