Can't View Roles or Features SBS 2011

not sure what happened but here is the whole post:

Greetings, I have a Small Business Server 2011, (which I think is just 2008 with exchange 2010) getting the problem of not being able to view or add roles or features.  I understand this is a problem with the windows updates and have ran the Microsoft Update Readiness Tool which produces the following:

Checking System Update Readiness.

I have completed the instructions to download, extract and replace the files several times, but to no avail.  I still have the error on the roles/features, which is:
Unexpected error refreshing server manager, exception : 0x800F0818

Any help will be greatly appreciated

Thanks

Have you rebooted?

Found solution myself.
