Problem scanning with Ad-Aware

I am trying to do a scann with Lavasoft’s Ad-Aware personal. The scanning always stops after it reaches a certain point in the registry, namely a CLSID. I have tried everything from running in safe mode to reintalling the software. Other antispyware runs perfectly well in my computer except Ad-Aware. I have tried to contact Lavasoft but is impossible to get an answer from them. Is there anyone that knows or suspects what is happening?

Thanks in advance for your help.
