NickH,
I assume that you have installed EZrotate in addtion to DBpro, correct? Sorry, had to ask.
The next thing is, have you activated it? When you purchase EZrotate, you should have been sent an e-mail with an activation code in it. When you install EZrotate, you should be propted with an activation window when it is complete. You have to put in your e-mail address (that was used to purchase EZrotate) and the activation code.
If you are not promted with an opportunity to activate EZrotate, you can go to the DBpro/compiler folder and find a file named TGConline.exe. Run this and enter your info. Things should then work fine.
a.k.a WOLF!
