Frequently I modify existing Activities,whether Default or Custom. If I do this with TSRE I get a curious message that "Track Sections-X or Y Track are missing" and then a crash. This has occurred on "Payware" Routes as well as on several freeware Routes. X Tracks is installed and here comes the weird part! When this happens,I go back to my MSTS Activity Editor,make the change and forward it to my Installation. It runs with NO Problem! No error message and no Crash. Just curious if anybody knows why and how to correct because I am stumped! Thank You All! Brian![]()
