Yes, I get that too. Hope it will be back up and running soon =)

Obviously others are having trouble accesssing it, too:http://forum.avsim.net/topic/421389-*******-tweaking-tool-fsx-offline/, http://forum.avsim.net/topic/422665-tweaking-and-tuning-tool-down

 

But looking at your computer specs, you should probably use the AVSIM guide or Word Not Allowed's guide instead, as those are aimed at and optimized for newer computers. Besides, as others have stated in other threads, the automated tool might be "dangerous", as you don't know what entries it adds, and what those entries mean.
