Hi - I am doing M4515311 on a dual P200 under Win NT 4.0 for Workgroups and Prime95 v. 15.4.1, and some time after iteration 2640800 I get an error message: Exception: Illegal function 0xC000001D Address: 0x0047CF27 I have stopped running the program as it just repeats this when it gets to whichever iteration where it happens. What should I do about it? All the best, George.
