Problem with add on 4 and xp.Installed RFG2 and it ran fine. Installed addon 1,2,3,4,online update,and all work ecept add on 4. It asks me to put in add on 4 CD when I try to run G2 and when I do it just reads the CD for a while and never starts. I can hit the cancel on the window that says to insert add on 4 cd and G2 will run with no #4. Serched this site,found a post that said to rename the file rf.ini,cannot find this file in any of the RF program folders.Rename it to what? RF site says edit fileread.INI,edit how?have a FILEREAD but not a FILEREAD.INI Had #4working on same computer before now no luck. Thanks Roy
