I bought Avast Internet Security and I have received licence file via email today. Next I have installed the Avast Internet Security 8.0.1483. When I try to enter license file I get such error:
"Unable to enter license file. Signature is incorrect. License file is corrupted or modyfied."
I have no idea if it is the correct translation of this error message as I use the Polish version of the software. Does anyone have an idea how to resolve the problem?
