Corel DRAW X6 suddenly stopped working after a year of use

Hi,
I had a similar problem with X5. I never did find the cause of the trouble.
However, I was able to uninstall it from the disk and then install it again.
In general, I have found that one gets a better uninstall from a program
disk. Windows uninstall via Control Panel leaves a lot of junk behind.
Good luck.
Phil
PS: On my HP computer, one can get a diagnostic check of the computer by
constantly tapping on the f2 key just after hitting the start button. I
believe that this has become standard for Windows but the f key varies with
the computer manufacturer. You can also get a complete check and repair of
all the Windows operating system files by using sfc.exe/scannow as Harry
London posted. If you can't find his post, look up sfc on the internet.
CAUTION: Don't download anything. It's all built into Windows. I've had a
few disasters by downloading programs which were going to speed up my
computer.
PPS: If you're not familiar with Restore Points, then you should learn all
about them. They can be a life saver.
