Hi there,
Unfortunately rolling back to 5.43 won't help in gaining access to any map tiles. Everything that you have cached should be still available, regardless of what version you are running. It may just be a matter of pointing TF to the correct map cache directory?
Most servers are operating right now -- you should be able to get MyTopo, Color, etc up there in AK.
The skewing problem is certainly an issue up there, sorry about that.
