Slitherine

prob with using multiplayer keeps askin serial number registered cant access any help

In which account have you registered your Panzer Corps serial?
I've checked this Oaggy account and you have only registered Panzer Corps Grand Campaign '41 and Commander Europe at War.
So if you want to play multiplayer with this account you'll have to register your game in this account. If you're not able to register it in this account that's because you might have already registered in another account.
How many Slitherine accounts have you created?

I have Panzer Corps Wehrmacht Panzer Corps Grand Campaign, then 30 dlc Panzer Corps Grand Campaign then 40 Panzer Corps Grand Campaign and 41. 1 Oaggy account do not have 2 accounts it Error 31: Serial Number Already Registered. how do put then in oaggy account not every good at this

From what I was able to check you've created several different accounts, Oaggy, Oagie, Bez89.........
I'm afraid we can't solve your problem through the forum, so could you please, send an email for support[at]slitherine.co.uk, with all your orders details and stating your issue?
Thank you.
