problem booting saispace2

There was some issue booting saispace2 last evening. Stopped at the Windows boot screen. Booting into Linux without any problem. Booted into Safe Mode - OK. Then tried Debug mode - froze while Yahoo messenger was logging in, and Adobe Flash plugin was trying to download an update. Tried the Enable Boot Logging mode - OK. Freed some more space on C drive after the recent updates - only 200 MB was free, made it to 1 GB free. Then booted normally, no problems.
