PSP8 error message

Hello there! This is my first post and I hope I am in the correct area.
I run XP Home and I use Paint Shop Pro8 for my graphics. All of a sudden I am getting the following error message when I attempt to use the "cut and paste" option: CException: 'OpenClipboard Failed' error occurred with command: Copy
It had been working without a problem but now. I have done a system restore twice, numerous scans and reg fixes and I am at a loss to understand what has happened and why.
I would be most appreciative if someone could give me an idea on how to fix this annoying issue.
Thanking you in anticipation of assistance.

Have you tried to get a patch for it? They could have fixed that problem in an update.

Also, you could un-install, and then re-install.

Thank you for your reply Vaerli, I will try to find a patch again. I have uninstalled and reinstalled the programme twice but still have the problem.
Once again, thank you for replying and have a great day!
