Error on map visuals: Map and filled map visuals aren't enabled for your org.

Hallo all,

Could you please help me in the following problem?

- I used map visuals in Power BI Desktop. It worked at first, I could display the maps effortlessly.

- Then, one day, without any prior indication, the maps I created didn't work anymore. Error message is as the following:

- I read on internet that the solution is to go to Power BI Service, so: app.powerbi.com > setting > admin portal > then activate the maps. However, on my app.powerbi admin portal, there is no option for map activation:

- Only me using Power BI on my own computer. So, I don't have IT department, or admin or whatsoever to go to. 

Can someone please help me with this problem? 

Thank you in advance.
