Oh man, can I relate to this one. First of all Roberto, I wouldn't freak out or anything just yet, especially since you have ample time before the date of the show.

I actually somehow lost my ticket between the walk from my car to the venue of the Fox Theater in Atlanta for the sold out New Year's show back in January. I thought I had put the ticket in my pants pocket, but I don't know if the wind took it away or if somehow I threw it in the dumpster when I threw some trash away on my walk to the venue. Not to mention the fact that i had just driven two hours from Birmingham to Atlanta. Needless to say, I almost threw up when I realized what had happened!

Long-story short, after about a 45 minute frantic search in the parking lot and the dumpster (yeah, it was great), someone advised me just to go to the box office and tell them what happened. All I had to do was show them my ID and the credit card that I had used to purchase the ticket. It wasn't really a big deal at all, but in the end, the stress of that evening probably took a few months off my life!

Good luck Roberto, but as long as you have some sort of proof (credit card, confirmation #, etc), I'm sure you will be fine.
