Hi Sergey
I tried to recreate the project, and received the same error message. I then deleted the foxuser.dbf and .fpt, and received the same error. Next I think I'll try changing the directory and going from there. Is it possible that VFP6.EXE is corrupt?

Regards,
Carmen

>VFP project is just a table and as any table it can get corrupted. I would try to recriate it. If you will still receive strange errors after that, try to delete foxuser.dbf.

>> O.K. tell me there is nothing to worry about. I have been doing a lot of work on an application using the project manager of course. Started to receive some unusual errors relating to problems not finding a class in a class library etc., and as I am trying to locate the class, I received another error dealing with the inability to write to an area of memory, when I clicked I was thrown out of VFP back to the desktop. I started VFP again and tried to open up the project I was working on. I then received a very scary error "Project File Is Invalid". Does this mean that I have to recreate the project, and let it build itself again? The error that is causing the problem is as follows: "The instruction at "0x77e9e8bb" referenced memory at 0x00000000. The memory could not be "written". This is in a message box along with the Cancel and Debug options. When I Cancel, out of VFP, and go back in, I receieved the Project File is Invalid Error. I'm pretty sure I can create another
