As a beta tester I had the game early, and had to uninstall it in order to get the final version. When you uninstall Entrenchment, the whole game goes with it for some reason (I think they've fixed that now).
In any case, problem is this: I try to install Sins, and it says "Decompression error" or else "file larger than expected".
I have rebooted Impulse, my computer, as well as deleting the Sins folder, none have any effect. I have also tried on different occasions, like every 4 hours or so since I got home yesterday, as well as this morning.
Any ideas? If not I'll have to figure out where I left my Sins discs... that could get messy.
