Aw naw! disaster

[Bowser]

My fixby, which after 2 weeks conditioning in the airing cupboard was very promising, has came a cropper. It's in a budget barrel, in the shed to condition for another 2 weeks. A week in to that period, had a wee taste and the barrel has lost all pressure, and the beer is flat!.

Probably too cold in the shed, and my patience with the barrel is now over.

Can the beer be rescued?.

It's around 19 deg in there, and yes, got the same reading for 3 days on the hydrometer.

Not quite, was still a few points too high, but I'd already had a stuck ferm with the wort, pitched more yeast, and it came down, then was steady at 1014

If I inject some co2, will the beer not remain flat? Would I not have to reprime?
