Insync APPCRASH - Windows 7

Hi,

Insync application isn´t running anymore.
I´ve reinstall Insync ( Insync-1.4.5.37069, Insync-1.4.4.37065, Insync-1.3.17.36167) (SO Windows 7 Pro)
but the problem remains the same.
I mean Insync freezes completely.
Is there a Log File or Debug Mode to understand why reason?
Thanks.

APPCRASH
Version: 1.3.17.36.167

I’ve also been seeing crashes since updating to 1.4.x.
But the problem stopped once I downgraded back to 1.3.x
