Trying to change out an old flakey Keyence KV-24R processor with a current KV-24DR. The Ladder Builder software I need to upload the program form the old PLC has to run on an XP computer. I was finally able to install a trial version of the software (after waiting a couple weeks for for access to an XP computer from the company IT department). The software ran the first time, but I had to restart my computer. After restarting my computer, when I try to run the Ladder Builder software, I get "Illegal initialization data" and the software shuts down. I have reinstalled the software a few times already. I have left a message for Keyence, but they don't support their own products in America (they are sending my question to Japan. Anybody have any ideas?
