When you Start LM, You get the white box that you could choose "Direct3D" and something elseI'm using Direct3D but when I use the other one the mouse is a bit slow and laggy.
Which one of the two are you using?
Okay I tried that one instead but I got another error popup, sorry... :(Select the 'Open' one and try.
Uh I would try reinstallingI tried reinstalling and still having the same problem, sorry. :(
It sounds like there are some files missing from the game.
I'm not sure though, I haven't ever seen an error like this
