I am using a very old version of Chrom Perfect (6.07) from 1995 and the activator is becoming intermittent. It is a DOS based system that runs quite well and would be very difficult and time consuming to convert to a newer system. Does anyone know of a source for such an old version of chrom perfect and activator to go with it? If you have something like that or know anything about these devices, please let me know.
