[EXCEPTION] "Font: Fontin Smallcaps, bold" caused fonts to look strange

Client crashed after 3.6.3c update. Happened after loading Oriath, right after the update.
Fonts look strange now all the time.

Running PackCheck.exe didn't help.

The actual crash:
In source code file: f:\buildslave\build\production\source\windows\visual\resource\fontresourcewindows.cpp at line 57,
Processing file: Font: Fontin Smallcaps, bold
Error: failed to get text metrics



Every time I run the game I see these in the log:

Was fixed by updating nvidia drivers + reboot. Not sure which one did the trick.
