Hello,
Specs: XP Pro SP2 German, Avast! Home (4.

, Integrated Windows Firewall.
When trying to start Avast! to enter the registration code, nothing displays on the screen. Process Explorer shows AshDisp as using plenty of CPU power. Avast! itself is running in the taskbar. If I try to enter the registration key via "Taskbar", "About Avast!", "License Key", I get an error message that the License key isn't valid, although I just got the E-Mail with it!
Does anyone know how to resolve this issue?
Thanks.
