HELP! Header Alignment Issue

I’m designing on a Mac. I’m having an alignment issue in my header file in Windows Internet Explorer with my PayPal button. It’s code I got from the PayPal site. (It’s not a PayPal plugin) It’s lower than it should be, which pushes the other elements in the header below it further down. I am wondering it I just didn’t code these other elements the best way. it’s definitely something I played around with multiple times. (God I wish everyone would just use Firefox).

I do realize there are some validation errors (but I can’t find them to fix them right now). This alignment issue existed when there were no errors. I am desperately trying to resolve this! Please Help!
