Error building Player: ArgumentException: Illegal characters in path.

Hi,
After updating to unity 4.2 when I try to make a build for android I get “Error building Player: ArgumentException: Illegal characters in path”.

I have no idea why this problem is happening but I need some help here :S

Have a look at this perhaps

:confused: Hope it works this is all mine was.
