Tippman 98 Problem

In January I purchased the Tippman 98 from Hustlepaintball.com (I played before) I decided upon the Tipp98 since I would only be playing in the woods and I'm a rec player.

Now the problem is this when I got the gun everything was fine, I shoot it few times 2 weeks apart. When I went to go play this past weekend. The gun will shot once and then nothing. I took the gun apart thinking it might've been the trigger still doesn't work. I remember I screwed on the house a bit tighter and still doesn't work. I have the double trigger, stock & m4 barrel as the only thing I've done to it. Nothing internally. I use HPA air. My gut feeling its the air tank since I cleaned it with goo-gone before and it rolled inside not through the actual top part.

I'm beyond frustrated at this point.
Thanks

Believe me when I say I've stripped down the gun and relub'd it. I brought in a HPA, CO2 tank nothing. Even when it has no air source nothing. I realized that I didn't register in time for warranty work, anyone know how much they charge for that and how long it takes.

Thinking of just cutting my losses and going with something better. I barely used it (3 times) and I checked the the HPA tank with the goo-gone and it wasn't the problem since it never got in the tank. I know it's fixable but at what cost?

What exactly happens? You put your tank on, pull the hammer back, and when you pull the trigger back the marker cycles once and that's it? Will the hammer go all the way back again, or do you need to do that manually?

Here's two suggestions.
