Hay Aaron my brother,
I installed the latest stable Version 2.6, but as I finished installing it, and it came up and said my registration key was corrupt and I needed to re-enter it.
Now I had just opened it for the first time with no Auth Key to begin with so that was strange, so I copied pasted my Auth code into it, but it said it was not right Auth code and crashed big time. what going on Aron? has to be a bug of some kind. Oops what happened?, humm going to restart my comp and see if that fixes it, but I doubt it, will post if it did help.
