Hi friends, I have an NT31 touch screen (NT31-ST121-EV2). Its system software's version is 3.2 My Support tools software version is 4.0 (or 4.7, I cannot remember exactly). Whenever I tried to upload the program from the NT31 (for backup), the following messagebox always appeared: "The version of NT31 system software and support tools do not match. Please check the version and upload again. Communication aborted!" Does anyone know how to solve it? Please let me know! Thank you very much for your help! Hai
