Hi Zertor, yes I installed the latest version 4.1 and didn't have any previous version installed.
Just in case I uninstalled the wallet and deleted the folder in appdata/roaming, rebooted and reinstalled.
I added your 2 official nodes ; pascalcoin2.dynamic-dns.net resolve to 127.42.0.5:4004 which I already had, and the other one doesn't work.
Of course I accepted to add an entry in the windows 10 firewall, and checked that "pascalcoinwallet" was allowed.

I will wait a few hours again and report back.
