Cubase Pro 8.0.10(64 bit) Could not load GUI Resources

I just upgraded from Cubase Pro 8.0.5(64 bit) to Cubase Pro 8.0.10(64 bit) and it now fails to initialise. I get the following message during Cubase initialisation:

“Could not load GUI Resources”

My Cubase has worked fine up to this point. This is my laptop installation:

Aspire E1-531
Intel B960 processor (2.2GHz, 2MB L3 Cache)
8 GB DDR3 Memory
500 GB HDD
Intel HD Graphics
Windows 8.1 64 bit

No 3rd party plugins.

Please help
