I logged in to Impulse yesterday and found there was a new patch for SoaSE and Entrenchment available. Naturally I tried to start the update process - only to have Impulse tell me that my registration for Entrenchment is not valid. This is very odd, as I know for a fact that my registration code has not changed and it was working earlier.
To make matters worse, after the update process finished SoaSE won't launch. It loads a black screen and then crashes.
Just what is going on? Why has my registration code for Entrenchment expired?
