If you, like myself paid out your hard earned cash for Chart master only to find out it's install to hard disk will not work on any drive but C: (contrary to what their support staff says), Follow the following procedure and remove the silly copy protect altogether: Make a copy of CM1.EXE rename it to CM1.XXX use debug DEBUG CM1.XXX -d cs:B967 you should see the following: 75 68 ... if not then you've got a different version than 6.1 and this won't work. If you see 75 68, then -e cs:B967 eb 68 -w -q RENAME CM1.XXX CM1.EXE You now have a copy of Chart Master without the copy protect. After arguing with the Stupid freaks about the fact that some people have a hard disk with other than a C: designation, I finally gave up and spent about 3 hours tracing the code and fixed the problem myself. Happy Charting, The Freebie Fixer
