Gadwin Print Screen

I'm stuck and don't know why. I've been using Gadwin Print Screen (Free) for several years on by XP Professional SP 3 machine. Suddenly it has stopped working when I am using Internet Explorer.

I have downloaded IE8 and the problem persists. Gadwin does not answer calls for help, tried 4 times.

When I have Explorer open and hit the hot key, my screen goes black. I can use it on an excell spreadsheet with IE closed and it works. Open IE and it does not work.

Any help would be much appreciated. I use the print screen every day and I'm lost.

Thanks in advance.
