Hello,
I have a unipi 1.1 which has been running fine for a couple of years, last night I did an os update (apt-get update / apt-get upgrade) which finished OK.

I subsequently noticed that my controller was no longer running, REXYGEN diagnostics could connect but there was no active executive.

I tried re-downloading the executive but it failed with an error "not licensed on target device -805), looking at the logs with Rexygen diagnostics shows "block MQTT is not licensed..."

The license dialog shows the device is fully licensed, there have been no configuration changes and it was working fine until the OS upgrade!

Why has it suddenly started complaining about an MQTT license?
Runtime version after upgrade is 2.50.12, system was compiled on Rexygen studio 2.50.10.12481

I would be grateful for any advice as I now have no heating!

Thanks

The problem was indeed a licensing issue, it is now solved thanks to Rexygen support - excellent customer service as always.

In case it helps anyone else, I eventually found the problem.
Under normal conditions, when Rexygen studio is started you get a dialog box asking whether you want to create a new file or open an existing one: In my case that dialog box was not displayed and the main window was frozen.

While trying different things, instead of opening the program directly, I tried double-clicking on an existing MDL file, the program opened and functioned normally.

I then closed the program and reopened it and this time I got the dialog box and now it works perfectly.

I can only assume that for some reason Windows was placing the dialog box behind the main window, as the main window is blocked until the dialog box is closed you cannot move or minimise it to expose the dialog box, somehow opening an existing MDL file directly unblocked this situation.

Hello,
I had been using rexygen (2.50.8...) on a windows 10 PC without problems, but following a recent windows update it stopped working, when starting the application I see the main window but it is totally frozen, I cannot click on any menu items / move the window or close the application. I need to kill it with task manager.

I tried deleting the application and reinstalling the latest version (2.50.10...) but the problem remains.

Windows error log shows:

RexDraw.exe

Rexygen Diagnostics works with out any issues
I have windows 10 build 19041.746, experience build 120.2212.5510

Any ideas??
Thanks
