Can u guys control my way on how to update (the client) without screwing the hole thing up?
Let's go:
I have found this:
https://bitcoin.org/en/release/v0.9.1 according to it, i have to shut down my current old client (done) then:
1. download the "bitcoin-0.9.1-win64-setup.exe" file from the link above
2. run the installer on that .exe file
3. afterwards start the client and it will sync it - and voilà, it's done ... right (??)
