There is no License option for me under Help

I had to reinstall the program after the last update failed

If there is no license option under Menu > Help, then you have installed eM Client from the MS Store. That version uses a monthly subscription which you will need to purchase from the Microsoft Store for Pro features, or you can just use it as is for the Free version.

If you have a Pro license from us, and want to use that, you will need to uninstall the MS Store version, then download eM Client from our website instead and install that.

ok I just paid the monthly subscription. How do I ensure that I’m not billed on the other one on a recurring basis?

Purchasing a license from us is a one-off payment, so there are no recurring charges.
