I get this error every time I want to play or spectate a 1.6RC game. I tried deleting the patch folder and installing it again several times. Tried reinstaling the game. I'ts not working. Also, every time it gets the bad image error seen in the image atached, and the antivirus takes the file "v16RC.dll" to the vault. In consecuence, the game starts in single player mode and displays the "you're not using que 1-6RC patch" image. Please help.

Every time

You need to put the patch's folder into the exeptions of your antivirus. Depending on the program this is done in a different way but you can probably google it.
