The file / program has some quirks that TCA does not have solutions for at this moment.
First identifiable bug is that it triggers as a malware file when downloading, so you may have to override your browsers firewall. We have scanned the files with 10 different malware detection software and all results have been negative.
Other issues are that if you switch out of Zone A, to a different zone, you must reset the program to access Zone A again.
If the program is not reading your XRC-152, verify that you are in the correct communications port under when you click the COM icon.
