Cannot continue the campaign in SP

[spookster]

Hello there,

i got a serious issue with the campaign.
When i go into the campaign menu the "continue" button is gone. Only the "New" campaign option is available.

I restarted the campaign like 4 or 5 times already. And the first missions get really boring. The farest i got is to Mission 16 in COD campaign and now the button is gone again.


Why doesn't it save my campaign - or does the button vanish when you loose too many missions?

Anyone knows what i can try to get it to work?

Thanks for your help.
