I also got an error when upgrading 4.5.3 to 4.5.5.  the installer does not run.  dont know why.

The type initializer for 'DotNetNuke.Data.DataProvider' threw an exception.

Yes, I unzipped the zip files again and it worked this time.  I guess some file was not copied over correctly.  Maybe I should have logged off the site first.  ;)

now the modules do not exist anymore.  I get a module error on every module.  On the Host login, I see all the modules are installed.  I will look at this later or maybe will install all modules again.
