Venice Unleashed

I spent all day trying to solve the problem I'm facing, obviously did not get success. I'm absolutely sure that more people are facing the same, so I decided to expose the object in question to the community, so that the solution arrives at all (we break the bread at all).
.
.
.
I exemplify my problem:
.
1- infinite loading (I own a computer that meets the needs of battlefield 3).
.
2- After having noticed this endless loading, cranked up the debug to know actually what I'm facing.
.
3- I get the following message in debug ----> "[1230/202717: ERROR: command_buffer_proxy_impl.cc <201>]
[1230 / * same: ERROR: webgraphicscontext3d_command_buffer_impl.cc <208>]"
.
.
.
.
Probably should have a way to copy the whole list, but there is only those two errors.
.
.
.
I respectfully ask for those who know how to solve this problem so that not only help me but for all who are willing to participate in this magnificent project.

The solution of my problem found in this phrase -----> "If you are running Windows 7, Ensure That You Have the Platform Update 1 installed found here."
.
.
.
The great cumber was the windows update (specifically my ... he seems to be buggy).
What I can tell people who are having the same problem I had:
.
.
.
Install the update plataform 1 (if you are runnng windows 7); this solved my problem.
I thank those who provided this information (about the platform update 1).
.
.
.
I hope that my experience will serve to help solve the problem of those who so with me, want to participate and help the growth of this magnificent project.
