I would suggest a clean install of rune, then patch 1.06 and 1.o7 then install HOV without any maps mods or mutators. If still no, I have not a clue what it is doing
I would've said something earlier but I didn't feel like posting because I hate posting here lately because most of what is on this forum is bullshit (thanks to the children). But I should've helped the ULF, sorry for not being quick on the trigger .
...if only the original Unreal engine would use "smarter" error messages, ones that actually generalize the error (with a reference number) then give details in a drop-down dialogue... because that has nothing at all to do with video (or doesn't readily seem so).
