wine users - Oct 2011 - Kindle failure

My Kindle for PC has worked fine in WINE for many months, although the offered
upgrade last month did fail to install; I didn't need it anyway. Now it has
suddenly stopped working, I think since latest Ubuntu updates, not the 1110, it
was fine with that for weeks.
What might this mean?

$ wine .wine/drive_c/Program\ Files/Amazon/Kindle/Kindle.exe
fixme:service:scmdatabase_autostart_services Auto-start service
L"CBUfs"
failed to start: 2
fixme:system:SetProcessDPIAware stub!
$

I have got around this by downgrading Kindle to 1.5
It was 1.7 I had been using and 1.8 was the version which would not even
install.
I would still like to know if the fixme could be actioned.

I would also like to say that I used WINE very successfully ten years ago in a
commercial environment to run Excel to build complex spreadsheets overnight from
Pick D3 data exported to csv on the same box. I found that Excel actually
worked, running macros, over ten times faster in WINE than in Windows, simply
because it could not wait for screen-completion with no feedback from Xwindows!
Even then, though, I could not use the latest Excel versions due to deliberate
Ms anti-wine measures.
