This is a long shot, but if you look at the text of your error message, it shows a double back slash. This makes me wonder if the SET statment in your AUTOEXEC.BAT or CONFIG.FP file(s) has an error in it.
It looks as if FP is looking for temporary files in the C:\FPD26 directory.
If for some reason, it turns out to be rendered as something C:\FPD26\\ then it might generate a file not found error. --- Larry
