One of my Sharepoint 2010 Site Collections has stopped functioning this morning and presents the following in the browser.

Server error:

When I look at the "Manage Databases Upgrade Status" for the content database in Central Administration, it tells me

Database is too old and upgrade is required

Other content databases are fine and the other site collections work.

After Googling, several sites have suggested to run:

psconfig -cmd upgrade -inplace b2b -wait -force

But this also fails on task 2 of 4 saying

An exception of type Microsoft.Sharepoint.Administration.SPUpdatedConcurrencyException was thrown. Additional exception information: An update conflict has occurred, and you must re-try this action. The object SPUpgradeSession Name=Upgrade-20130307-113655-410 was updated by MYDOMAIN\Administrator, in the PSCONFIG (7228) process, on machine MYSERVER.

I am running out of options, short of doing a restore from backup which isn't the preferred solution as this is our company intranet.
