After upgrade to v8 - client no longer starts!

Hi,
PC received an update and upgraded to v8 (8.0.2951.0) yesterday. Happily used for the remainder of the day.

This morning; the client does not even start!
EMCLIENT.EXE appears in the tasklist for a seconds and then disappears.
I can see check_db.txt being created in the MAIL folder but with 0KB and a file entitled cef.log is created in LOGS.

cerf.log contains the following -
[0717/071151.909:ERROR:icu_util.cc(172)] Invalid file descriptor to ICU data received.
[0717/071151.910:FATAL:icu_util.cc(309)] Check failed: result.
Backtrace:

I’ve restarted a number of times with zero luck!

Help!

So after a third attempt to repair client. I uninstalled, rebooted and reinstalled and only then could I access my mailbox again!

I’m not really happy with this and may jump ship to another client. I didn’t realise a new license was required too for V8!.

Not really impressed.
