The crack does not cause any problem. It patches the soft like the version 2009 published by rl-team with just 6 byte modification to the target (17) files.
If you simulate the CB4CE entity (from libraries window) manually and stimulate the input pins (from stimuli window) manually you'll see that it works fine but I admit that there is a script error, why I don't know.
I always go back to modelsim which I now license - it runs on all platforms and such, but you can't beat the editor on aldec - I also like using the waveform viewer for dumps from identify debugger. Hardly though justification for the price tag
