Thanks Sorna,
I already found that thread and switched to a different account with US English Regional settings, which immediately yielded this error on startup:
(9/5/2011 3:20:31 PM) Message: The service cannot be started: XML parsing failed at line 1, column 0: A document must contain exactly one root element.
. (Source: \\?\C:\Program Files\Microsoft SQL Server\MSAS10.MSSQLSERVER\OLAP\Log\msmdsrv.log, Type: 3, Category: 289, Event ID: 0xC1210000)
And I traced this error message with someone else has addressed here:

The above implies some sort of corruption has occurred to SSAS.
I briefly looked at de-installing and re-installing my SSAS 2008 instance but couldn't see how I could selectively remove SSAS without removing everthing else (I use the DB engine, SSI, SSRS among other things) and I'm reluctant to go down the full blown
de-install/re-install SQL Server route after reading so many horror stories of people struggling with picking through registry entries and then eventually wiping and re-installing Windows afresh to recover. If I go to Control Panel - Programs and Features
- Microsoft SQL Server 2008 (64 bit) - Uninstall/Change I am presented with three options: Add, Repair or Remove. I thought I'd be able to get into some sort of installation wizard where I could selectively add/remove components but from what I've read,
selecting "Remove" will simply remove SQL Server in its entirety, which is not what I want!
The thing that puzzles me is how this issue occurred overnight on a machine that I've been running all this software on for upwards of 12 months with no such difficulty. I was hoping it was merely a side-effect of a Windows Automatic Update and therefore
easy to identify/rollback before I get into the who re-installing thing.
