In Paint Shop Pro X and XI it is possible that the programme no longer wants to run. Most often you will get the folliwing error :
Buffer overrun detected!
Program Pro Photo XI/Corel Paint Shop Pro Photo.exe
A buffer overrun has been detected which has corrupted the program's internal state. The program cannot safely continue execution and must now be terminated.
Luckily there is a solution:
You probably did this during the reinstallation process, let's try clearing the cache once again.
A. Close Paint Shop Pro Photo XI if is currently open.
B. Go to Start | Run, Type appdata and click Ok.
C. Open the Corel folder.
D. Delete the following files:
E. Select the Paint Shop Pro Photo folder.
F. Select the 11 folder.
G. Delete the cache folder.
H. Close the open box.
This should do the trick: start the programme again and Corel PSP XI should work again
