Please try this DLL with the latest build available.
First I tried replacing the DLL in version 25.0.48.
Did a Load Program Guide, which completed, but with the same empty result.
Then I realized there was a new MC version (25.0.54). I installed it and again the DLL was replaced.
Did a new Load Program Guide, which stalled before it started counting the transponders (xx out of yy completed).
Rebooted and did a new Load Program Guide, but this time logging. It stalled again just like the first time.
Left it for more than one hour without further progress, before i did a Stop Loading Program Guide.
Log file attached.
