Thanks all.
I will try bigboywooly's suggestion first to see if I can identify which ship/file is causing the problem. If not, I will have to look at the eqp files or take jimbuna's idea of loading them one by one. I took a back-up before I installed the new ships so if it comes down to it, I may just overwrite the files and start adding in the new ships again and test it after adding each new one - I'm sure it must be one of them that is causing the problem somewhere.
At least the game is working, which is the important thing !!
Thanks for your help.
