As noted by the initial reply, the only way to have 1.05 at this point is to install from a retail disc and update via the standalone, or to have backed up 1.05 before updating to 1.1.
I've tried the patches, they don't patch 1.13 correctly, and it crashes at the start.
Installing a standalone patch over a newer version will generally break your install. Doing such is pretty much never a good idea.
Well since you updated past 1.05 that must mean sins is registered to impulse so it digital now you can unistall it and reinstall to the desired patch.
Only the latest versions are available on Impulse.
