Query: Disappointed

This is not the first time I have had to buy a replacement lamp for my projector.BUT this is the first time that I ordered (which according to the listing Its the right model # lamp) one that I had to force it in. I would've returned it but I didn't try to install it until about 40 minutes before a HUGE presentation for my job at my hotel.
