hi everyone. ive installed RA2 again and still got some of the old maps that i use to play saved onto a old hard drive. the maps are in MPR format. i remember before i only had to copy and paste them into the RA2 folder. now ive gone into Origin Games/ command and conquer/ maps and pasted them there. now when i click on skirmish the maps are not on the list. can i still use the old maps?
