people playing EU VCT tomorrow come here

hey mens playing eu vct))))
I'm downloading tournament client and on the link for how to install the client (https://www.vct.gg/statics/tournament_client_guide) it says you download first strike but like this is VCT so do I download the VCT one or first strike as the VCT website says lol

When I try this I can't login to the account it says that I have no permission even though im in the tournament
