There is way too many variables for anyone to help you with the amount of information you have provided. There could literarily be thousands of errors that makes the editor crash. Also, no one here mixes fh2 and vbf2 stuff daily (or rather ever) so it's nothing we are familiar with.
That bf2editor error is common, and is just a warning. Check your bfeditor folder, there should be a logs folder with some text files, at the bottom of that you could find something useful to the actual crash.
If you can't find out through the log file what's wrong then i am afraid you're going to have to go back until you get a working installation again.
And please do not open multiple threads about the same or very similar problem, that is just common forum courtesy.
