I think you made the same mistake I made as I didn't RTFM either. Excuse the rudimentary markup in the pic :).
1. Open up Wigidash and create a new blank WigiDash.
2. Select 5x4 and drag the "AIDA64" box into the area denoted by 3.
From there you can go to step #2 :)
2. Launch AIDA64 software.
3. In AIDA64, open “Preferences”.
4. Under “LCD”, find the “Gskill” tab and check “Enable Gskill LCD support”
