I'd like to take a look at it, but for some reason I can't DL the file.
It always comes corrupt.

That's strange I downloaded it to check it and it opened fine .

I am sure it is the weapon that is preventing the multiple primary bank problem.  The new weapon was a mass driver so I just copied and modified the Kayser in the weapons tbm.  If I use another weapon that I have made the 2 banks work fine.  Here is the tbm entery.

I can get the effect that I want by modifying one of the laser weapons I have, so there is a work around - I would like to know what the deal is with this mass driver though???

Did you actually edit the mission in FRED and allow the weapon in the loadout editor?  Although if it's loaded on the player ship by default FRED should add it to the loadout.  I know current builds do but there were some bugs with it previously.  Not sure if it was fixed pre 3.6.10 final or not.

Yea, the whole mod is freaking out.  The ability to have 2 primary banks is coming and going.  I think it is a problem with one of the missions - the last one I made and one of the capital ships in there.  If I delete the cache I can get multiple banks, sometimes, if I start out in a clean 2 ship mini mission.  If I go to the big mission I either have only 1 bank or no banks.  I have run the debug and I get 6 'vec3d something or other errors' followed by a killer 'wep <=0 something or other error' and I happen to have 6 turrets on the cap ship so I think that is the problem.

I am going to shelve the project until after the holidays - I need a break.  I can't possibly finish the project until 3. 6. 11 comes out anyway because I am depending on being able to run video at basically anytime during the game which I have heard you will be able to do in '11.

Thanks for the suggestions and help!
