Reload, any chance you you have Laser or other software already logged in with that ID? I've seen the immediate executor disconnect, in that case.
I own that userID, and when I login through Laser, it was ok. I tested it between Laser and my system, It seems that the problem was just at the sys' side.
buddy, are you using the GTAPIB (the C basic version), or the GTAPI (ths C++ verison). I am using GTAPIB, which is dowloaded from the gndt's website, and it seems that it doesn't work!
