Hi. I am Programmer and develop programs for Mettler-Toledo ID7 weighing tool. I use Keil uVision V2.14 as my IDE. I have registered version with serial number and dongle. It was working fine but now I am getting error message like you are using evaluation version of uvision, which is not true. I checked the dongle with application SENTINEL MEDIC, and it is detecting it properly. Please help me with this problem. Thank you very much.
