I recently reformated my pc; problem is that now I cannot get tfd to install. My progress meter during installation gets only as high as 76% which looks to be while the terrains pff file is loading. Then it stops loading and I get an error message #117. I tried to copy the cd to my hard drive but that isn't happening either. My pc is a P3 933mhz, 384ram, G4 ti 4400 graphics card. Any suggestions would be helpful...please and thank you.
