Your beer should be fine, it has probably been producing co2 from the DME so should have a nice blanket of gas protecting it.
I would change the cap for the injection model, sanatise and smear the threads with a little vaseline, you can smear a very small amount on the seal as well. Put it on hand tight then give it another 1/4 turn, you just need enough to seat the seal.
You will do no harm adding more DME as the cap will vent excess pressure. I would add about half of what you have added already, boiled and allowed to cool. I would also inject some gas to check if you have a seal, any excess will vent off. Leave it for another week in the warm then somewhere cool for another week or so.
It may be a bit lively at first but to be honest it always is from these type of barrels, the trick is to put you barrel close to where you are sitting so you don't have far to walk.
