Generally, I'm grateful for patches. CA isn't obligated to keep patching a game that's been out for five years. But today, this patch broke DeI for many users, including myself. It's ironic that CA interviewed DeI to promote their new launcher, and as of right now, if you got the Steam version, DeI won't show up in your launcher.
I'll have to re-download the mod via TWC, as that version is still working. So in my current irritable mood, I'm more grateful for TWC than I am for CA's patches.
