for the record, every program has bugs. But what you are seeing is more likely to be a syntactical error, rather than a bug.

out of curiousity- why would you pay so much for a program that you have no idea how to operate? people usually trial an array of different solutions and narrow it down to the best one; THEN purchase it.

Somehow i don't think you randomly selected 3dgs and forked out $800 or so for the professional edition...
