Has anybody come across a problem whereby R2000i (cidilla locked) gives a fatal error saying to the effect the authorisation code is incorrect. The PC will then dump out back to desktop. Restarting may be ok for a day or so then it happens again. 25% of the PC's are doing this and the problem is getting worse. The 2000i patch has been installed but to no avail. I won't mention the plotting problems, long winded authorisation method, support paths changing to 2000 instead of 2000i, command line disappearing, express menus and toolbars disappearing, apart from this it is OK. I have another 60+ to install at another site but won't be advising to do so until all these glitches are sorted out. PS what happens to the authorisation code if any of the hardware is change because of upgrade of failure?
