Not sure if right board or not.
Both mirrors of the Slayer download are not working, and the auto updater is obviously using one of the websites that are down. I actually had to delete the slayer zip because it got corrupted somehow, and I would rather have the updated version rather than one from the RTB archive.
If you were able to acquire the most recent Slayer then posting it would be appreciated.
EDIT:
Here you go.

Can confirm this is the most recent version. Chrome seems to false flag this as being malicious. To my knowledge, there is absolutely nothing malicious. I think it's flagged because of the bat file which just makes the file it is in a .zip file. Thanks Legoboss!
