All DLLS in site fail to load, exception 0x80070057

Question

My C# web application stopped working for no apparent reason, while a similar
application on the same server still works. Looking for ideas what could be
going on and how to fix it.
Yesterday I launched a build of the site with some minor updates. The server
apparently went down during the build, because for a few minutes the TeamCity build manager
displayed a message indicating the connection had been lost. However, it
recovered and resumed the build.
After the build, I was no longer able to load the site. The home page now
seems to be the only page that can load, and it displays incorrectly because the
scripts and stylesheets fail to load. If I check the browser’s error console I
find reports of multiple server error 500’s, where the referenced css and script
files are failing to load.
The server is IIS on Windows Server 2008.
If I go to the server and open the site there, the page gives me error
messages saying, “Could not load file or assembly ‘Antlr3.Runtime.Debug’ or one
of its dependencies. The parameter is incorrect. (Exception from HRESULT:
0x80070057 (E_INVALIDARG)).”
Initially it was reporting the same message for a different file,
AntiXssLibrary. I removed that DLL from the project, and the site switched to
complaining about antlr instead. It looks like the problem isn’t either DLL, but
something else.
On my machine, a nearly identical copy of the same code works without
problem. Another copy of the site on the same server, a slightly earlier version
of our software, works just fine.
I deleted all of the temp files recommended for this error, redid the build,
restarted the machine, and deleted the bin directory and repeated the build. I’m
skeptical that uninstalling or reinstalling any versions of the .net framework
would help, given that the other site works—any problem with the frameowkr ought
to affect both of them.
I turned on assembly logging, which gave me lots of additional information
that didn’t help at all.
Any suggestions what could be going on?

Hi Laura Eve,
I have google this error, SomeOne encountered the same problem, I have collected some solutions. Please have a look.
   1.  empty your %TEMP% folder:
close all programs that you are using (the one in the system tray included)
Click the start button
click Run
type: %TEMP% in the box

  2.  Now a the directory for temporary files opens:
select all files ( CTRL – A)
press the DELETE key on your keyboard
acknowledge that you want to delete all files

are deleted, then SVN update.
