I have a problem with my K4PC - I can't open it to use it as a reader, or see if purchases have arrived.
I can open my account OK , and I hit "Deliver to ..." but can't open the application itself.
[ This also means I can't Add stuff to my Calibre library, as any new buys have to go through K4PC - as far as I'm aware, anyway. That's a real bummer ...]

I am running XP(3) Home, dinosaur I know, but it was working fine at one time, and this is the only thing I've had trouble with so consistently.

I have had this twice before, and each time I've gone through Amazon Help, and - eventually - we've got one to "stick" and function.
The last time I "liaised" with Amazon, very recently, it took 6 uninstall /installs before one opened as it should. Until this, each new version would open a couple of times, then die.
The Amazon guys were mystified, as normally just one download does it.

This last one was OK for a few days, and I managed to catch up with importing books etc... but last night the damn thing packed up again ....

I just thought I'd ask if anyone has any ideas, before I try another ........ session of un/installs.

Is it possible it's the OS , and I need to finally upgrade ?
My malware/A-V etc.. shows no problems, and everything else works just fine.
