how to recover server manager

Hello expers,

After windows update for windows2008R2 server standard  ,
I am facing the problem that server manager is not working after windows update.
error says;
Unexpected error refreshing Server Manager: Exception from HRESULT: 0x800F0818

I found the solution following,
http://blogs.technet.com/b/roplatforms/archive/2010/05/12/how-to-fix-server-manager-errors-after-installing-updates-hresult-0x800f0818-hresult-0x800b0100.aspx
and I have been trying to do following this site , however, I cannot complete this.

In this middle of the web site, there is description like followings

- Unpack them using the following command:
Expand -F:* UpdateKBXXXX.msu x:\DestinationDirectory

I put Package_for_KB2524375_SP1~31bf3856ad364e35~amd64~~6.1.1.1.mum
file in the current folder and change this command to actual path.
Expand -F:* UpdateKB2524375.msu c:\test

but, error is shown , "Cant open input file:updatekb2524375.msu."
Are there any mistake of my taking steps ?
How can I do this exactly ?
