I have an issue with designer auto upgrade.

I downloaded sencha designer beta, version and ended up with Build 268, I was hoping that auto upgrade should sort this out.

I am behind FW, and added the proxy configuration when I started Sencha Designer the first time.
It looks to be that I have some sort of FW/proxy issue.

I am on windows XP
Is there any log files och config files that I should check to verify the case of the problem?
