Initialize Outlook Web App are not met. What to do?

I have win 2008r2 and exchange 2010.
When you try to go to the portal owa I get a message that "Initializing Outlook Web App failed".
Script UpdateCas.ps1 launched.
Owa re-installed.
Most often, the reason appears that the problem in themes. In fact the file themeinfo.xml in place and contains a string .
In what direction recommend to dig?
