Error when closing µ

[craft]

I keep getting an error when i close utorrent: it says -

Application Error : The exception (0x0eedfade) occurred in the application at location 0x7c81eb33.

then it says: Runtime error217 at (and different numbers and letters).

This started a month or so a go and is lately occuring more frequently.

i've been using v1.5 stable since it came out and i even reinstalled it, but it didn't work and i don't have any malware or viruses.

Can anyone help me? what's the problem
