ultrasurf windows has been hit or miss for me too. I switched to Hotspot Shield for a bit, and it’s been working fine. Not the same as ultrasurf, but it’s a decent alternative.
If you wanna stick with ultrasurf, try using a different port. Sometimes changing the port in the settings can fix connection issues.
