....

What led me to github rather than megashare or googledrive was by doing a google search for the miner. The github search result was one of the ones listed. I somehow went with version 11.8, not 11.9. I upgraded from 10.1

Yes, you've probably downloaded a hacked version (never seen official versions of claymore on github)

Alright, so I'm trying to update my miner to the latest version but it doesn't matter which one I download when I execute the .bat it says "...Claymore miner v 8.1" even if I download the v.11.0 or the 11.9"
Anybody can tell me how to download and install the latest version? The old ones doesn't work right now, thank you so much!

Go to the first page of this thread where official links for download are indicated.

For both:
The first rule to follow is always to download the miners from official links indicated by the developer.
