Aren't we running MWLL 0.3.2 by now? Not sure what else could be broken. Never seen that before. I would recommend a full reinstall. You probably only installed 0.3.1 and nothing else.
1) Install Crysis
2) Install Crysis 1.20*
3) Install Crysis 1.21*
4) Install MWLL 0.3.0 Full Releas
5) Install MWLL 0.3.1 Patch
6) Autoupdate to 0.3.2 release OR use the ZIP (
here)
You probably miss the files from the 0.3.0 release.
* Only needed if you use the retail version. Steam is already patched to 1.21.
