Mitsubishi GOT Communicater Error after reading and writing

Hello All

We are running into a series of problems when reading from GOT 15 series HMI's then writing back to the same GOT. After writing to GOT we are getting are getting a 402 communication error. The GOT will no longer communicate
with the PLC. A specific example is a GOT 1572-VNBD connected to an A series Mitsubishi PLC with standard RS232. We are using GT Designer3 version 1.45x programming software.
The problem has something to do with the OS version.
Any Help much appreciated.

Thanks

Nevermind, found the problem.
