SSRS 2008 R2 'My Subscriptions' page blank - Fix

Really annoying bug this one, fixed the same way as Ant describes at...
The users were authenticating in Report Manager as SOMEDOMAIN\MyUser, while the ReportServer database was storing the users without the domain.
All I had to do was prepend the domain to the applicable users' names in [ReportServer].[dbo].Users.
