if you can't install the game, as you say, then you can't log in either, because you can only log in to the client after installation.

Did you buy an account on the account creation page, and did you download the game from the same link on my 1st post? See below:

ACCOUNT CREATION:
https://accounts.onlinegaming.wizards.com/accountsignup.aspx


DOWNLOAD OF THE GAME CLIENT (WINDOWS REQUIRED):
http://magic.wizards.com/en/content/download

I bought an account yes, and also keep attempting to download from the screen but it gives me that error message.

The actual error message is, The Signature of setup (7).exe is corrupt or invalid.

pretty messed up that I just paid $10 and cant even access the game

when you click the download (WINDOWS) link on the page above it should let you download a

setup.exe file (422 KB large) which you should save, probaly on your desktop. that setup file when double-clicked will start the longer client download process (~150 mb).

let me know where the error message pops up during this process

When I click the download now tab, it brings up at the bottom of my screen the download process, but then a milla second after it gives me a the signature of setup.exe is corrupt or invalid. right after

i just did the same thing right now. the setup.exe file downloads fine on my browser (mozilla firefox). sounds like a virus problem or something specifically wrong with your browser or pc (settings or otherwise).

hard to say but that's my guess.

edit: i can even send the file to you if you wish, but if you have a specific pc problem i doubt the installation will complete properly in any case
