Missing Posters

My SickRage is installed on Win 10. Lately when I add a new show, it loads, but no poster??

we can’t proceed with the update. unable to check remote db version. error: assertionerror(u commit hash wrong length: 4 hash: none’,)

Please help

What version are you using?

Echel0n!!! Long time no see. I know I am using an old version, but how do I update to latest???
