Those are official mods.
You may want to try uninstalling the game then get a copy of 1.3a direct from the Paradox website, then only apply the 1.3B AI update. THat way you do not need the hotfix, since 1.3a includes it.
You can also rename the AVI folder to AVI_back, make sure your video driver is up to date, and your operating system. and that nothing is running in the background.
If you still have a problem then you should report it as a bug following the instructions outlined in the sticky thread on "how to report a bug"
