I would reinstall with the new installers. Install Version 3.0 and patch to 3.1. That's it.

Yeah, with so many patches applied ins sequence you'll probably end up with a messed-up installation.

Better to download the new installers.

nope, sorry, but the new installer + latest patch is broken.

it's missing texture references to moving particles for certain spells and items.

I'm experimenting with reinstalling the latest base and the latest patches for base +wm +wm2 to see if there is a way to fix it, but just saying... the OP has a point.

No it isn't, on both points. If you are experiencing difficulties, then you aren't installing the correct files, or in the correct manner.
