Brewing troubles

Good morning,

I just bought my first keg and put a pale ale in it the other day. I left it at a friends house who does not know much of brewing. Well I came back a few days later to find that there was a leak in the gas line. I pulled the release on the top of the keg and no CO2 came out and on top of that the brew store was closed for a few days and that's where I get refills. Is my beer ruined now that it has sat for 3 days without pressure?

As long as the keg is kept closed there's no oxygen getting in there, so it will be just fine when you get your CO2 setup straightened out...

Cheers!
