Reality Factory

I downloaded RFEditpro yesterday and after like 15 minutes i tried to preview a room and it said error compiling level

Please help!

What exactly is the error? Does it complain about missing entities? Does it complain about leaks in the level?

Did you read any of the tutorials? You need at least 2 entities in your level (they have to be inside your level!):
