Here's the deal.
1) You can send it to Bushnell and then they can fix it, and you will pay whatever it will cost, they may even upgrade you at a discounted cost.
2) You can try to repair it yourself. It's really not that difficult to do. The nitrogen can be repurged by going and filling an airtank at a truckstop that uses nitrogen for tire inflation. There are several that do use nitrogen. Remove the screw for the purging port and compress the air 5 times. Each time let the air out, the fifth time you will have 99.9% nitrogen in the scope. Note that getting the lens back into the perfect focus is a pain and takes patience. This has to be done before the purging. Also the type of cleaner you use is critical. It must be coating safe.
I would call Bushnell and inquire first. If nothing else then you can attempt this and possibly save from throwing it away.
