Critical Error Message

Hi,

Hope I'm not restarting a thread topic that's already been discussed, but I haven't been able to find my particular problem on the forum. If it has already been covered, someone please point me in the right direction.

Meanwhile, here's my problem, which only started after I installed the updated version of CCleaner. Every time I close the CCleaner programme after using it, I get a critical error message that says 'CCleaner is attempting to read from or write to a file it does not have appropiate access to' or words to that effect.

Could somebody please help me with this? I don't know if it's something to worry about or not, but I would like to get rid of the message.

Thanks in advance.

Are you using XP or Vista?
