Visit My Harbour Charts

I have installed qtVLM v 5.12-17 and I have purchased the 'Visit My Harbour' charts. I've installed to the the folder "C:\ProgramFiles\qtVLM\mbTiles" I have activated the charts via the configuration tab. Sometimes the Chart will show. but if I restart/turn off the laptop, when I restart the charts do not show. When this happened yester I recopied over the hdx and VMH file to the folder, activated again and then the chart came up. I've just gone in again and the charts are not showing again. I have copied the files over again , but charts are still not showing. Any idea on how to permanently fix this?
I have Windows 11 24H2
 

Hi,

Does it happen also when you just close qtVlm (menu->qtVlm->Quit) and restart it ?

Yes. Quit or Quit without saving. At the moment I cannot get the charts to load at all

The 'M" icon is on ?

M Icon is showing Blue in colour

Yes . The M Icon is blue in colour. If I click on once it stays blue and has a number 8 on it. If I click again it goes pink
