If you get a "Can not find/load text fonts" error message, then it could be one of three things:
1. Your Fallout2.cfg file has been modified and is no longer referencing the Master.dat and the Critter.dat as being in the correct place. These two files should be in the main folder where you installed Fallout 2. Change the path in the Fallout2.cfg to reflect the proper path for these files.
2. You need to have the CD in CD Rom drive. Even if you have a huge install, try inserting the CD.
3. Your Fallout2.exe or Readme.txt might have become read only. Right click on each of them and select properties. Check the attributes section to be sure that Read Only does NOT have a check mark next to it.
