Error 3315 Message

[dancagle]

starting to get a little flustrating because when I try to merge it keeps stoping on certain files and will come up with the message " cannot be a zero -length string) 3315. I've tried to rebuild the database also. When looking at the c: drive I have the MTU file under it but I also have under c:/programs the Micro tecnology Unlimited file that has the demo file in it with a songs file also. Should this file still be here or can I delete it?
