Problem upgrade version 8

I just paid for 2 licenses from version 7 to 8, and now the program doesn’t work for me. Keep telling me to renew …
Please help me, I have everything stuck

Please see @Olivia_Rust comment at Bought 4 upgrade licenses for version 8 but am still on 7

Hi Fernando,
we apologize for the inconvenience, there was a bug in our online store that was still giving out version 7 licenses/upgrades instead of eM Client 8.

This has now been fixed and all licenses purchased in the past 2 days have been fixed to be valid for eM Client 8.

If you encounter any issues with a purchase or eM Client license, please don’t hesitate to reach out to our sales department directly - sales@emclient.com.

using the email client on your mobile of course
