Cheat Engine

[pseudokinetics]

Hello,
I was using CheatEngine on C&C Generals: Zero Hour. I have never had debugger problems when attaching previously.

In this instance, I had scanned a value down and was using the memory viewer. I found an operation between two registers that I wanted to investigate so I right clicked and selected "toggle breakpoint". I then continued to run the game until the affected address was used and predictably, the game froze. The only problem was that my computer froze as well. I then had to end the game and cheat engine from the task manager to restore my computer.

Now, any time I attempt to attach the debugger to C&C, I get one of the following errors:

Error attaching the windows debugger: 87
or
I couldn't attach the debugger to this process! You could try to open the process using the processpicker and try that! If that also doesn't work check if you have debugging rights.

I have received these errors with both the windows and VEH debugger. I have also restarted the game, updated cheatengine to 6.5, and shutdown and restarted my computer.

Is there anything I've done that's permanently affected the debugger?
