When I try to update Panzercorps I get the message:
Error: Update information for Panzercorps could not be downloaded. Please contact matrix games for help.

Currently on V 1.26

Win 10
Intel i5 760
8GB ram
500 GB (100 GB free)

is that using the ingame auto version? if so alter your O/S firewall and give it permissions to run, or download and install the update manually from here
