well, after you downloaded it, you can stop uploading - cancel torrent or sth
then go c:/downloads (or wherever you saved this file you just downloaded) and run SRO_GlobalOfficial_v1_110.exe
it'll say you have silkroad on your computer already, so you have to reinstall it etc.
after that, new version will be about to install, wait and enjoy playing (if it will work ofc)
