Recon1994 and Pishpot, I do not see Entrenchment associated with your account. This usually happens if it was purchased with a different email address. If you guys could PM me any alternative email addresses you may have used I should be able to merge your accounts up and you should be good to go. Alternatively you could send an email to support@stardock.com and we will get to it ASAP starting tomorrow.
To use the latest update for Entrenchment and not have it crash, you must uninstall Sins via Impulse, reboot your PC, then re-install Sins and then Entrenchment.
