I have the rather annoying problem of getting an error nearly every time I go into the Sirius Sector space, say from logging on and trying to load up my character, or on the rare occasion I do get in, from transitioning to Sector space.
One time I managed to get into the game and load up Sirius Sector, but as I was doing some chores while waiting on the verifying (which I did turn off, btw) I finished the chores... only to sit down at my computer and right at that moment, the game crashes with the now very familiar "Fatal Error: Error decompressing data"
Maybe it's not just the Sirius Sector, but it looks like it doesn't have a problem with Spacedock. Further testing will commence.

I made a new character and it loaded just fine into the tutorial, I then logged out to log back in to my other one. Again, it crashed with the Error decompressing data.
I've taken my second character through the tutorial and Spacedock worked fine, Sol system worked fine, but when I tried to warp to Sirius Sector space...

That second line was new to me, though :p
