Calibre wo'nt launch
I use Calibre since many years on several machines, and I appreciate it.
I needed to reinstall Windows on my computer, then reinstall Calibre.
Calibre wo'nt start, error occured when constructing main UI, see debug below.
I have tried several times with 4 and 5 versions, deactivating antivirus. Could you help me?
