Alright, after a short while away from the game I recently dug it out again, most specifically for Entrenchment.
Impulse seems to detect that I have SoaSE installed, but wehn I go to update it tells me that I need to register.. fair enough. When I go to register, however, the physical copy of the game's registry key (the one inside the case, right above the CD, PC SINS SOLAR CODE STKR) seems to not be working. Every time I enter the key and click register, it tells me that either the Key is incorrect, or the e-mail address I've entered is incorrect.
I'm fairly certain the email is not the problem, and I know I have not mis-typed the registry key over a dozen times.
If I could get some help having this registered to my name, I would be delighted. Any help that might allow me to fix this issue from my computer would be helpful as well
