I downloaded fighter factory and installed it on my XP machine, dual core, with 1Gb of ram. It seemed to install fine, but when I go to run it, it keeps popping up an error that says " The paramter is incorrect" and wont load any of the tool bars and/or the other windows or tools. They come up blank. Any insight would be appreciated. I did have it working at one time some months ago. Recently decided to use it again.
