Bulk Rename Utility

I have been enjoying BR for a good while. It's so handy. Suddenly I get an error code and can't rename anything. Any idea what has changed on my system. I am an Administer user. I am not aware of any change I could have made to the system or disk or folders in use.

What version of BRC32.exe do you use?

>Suddenly I get an error code
What does this error says?
What have you done exactly to get that error?

>Any idea what has changed on my system.
What kind of system is this?

I am not as well.

Thanks so much for replying. I use Win 7 64 bit. I hadn't made any changes I could think of in the last 24hrs but somehow that one drive got it's permissions changed. I fixed it and all is well.
