Did you try to change the font settings to their original state?
Here are the settings for it:
[FONTS]
Font1=BankGothic Lt BT
Font2=Lucida Console
FontMenuSize=12
FontConsoleSize=9
FontBigSize=28
FontWeaponMenuSize=8
FontConsoleSmallSize=7
FontHeightScale=125
FontMenuBold=1
FontConsoleBold=0
FontBigBold=1
FontWeaponMenuBold=0
FontConsoleSmallBold=0
KillConsoleNameSpace=8
Make sure that when you reinstall Soldat, you not only unistall it, but also delete the file directory from your system. Reinstall it, and then restart your system if necessary.
If that still doesn't help, give me the link of the specific mod that caused this problem and I'll try to find a solution from there.
