Like most I guess, I have a fairly standard startup program that I use for all my projects - my program has worked fine up until now - (I haven't changed anything in there)

I am getting a strange error

Error number is 1 - file does not exist
The line of code with the error is DO d:\vfp6projects\foldername\project.exe
There are no spaces or anything like that...
The line number of the error is 0 in my startup program!

I am stumped - any ideas?
