Problem with Facebook Event Creation

I created a couple of events on Facebook and was going to promote them today. But, since I learned that my Uncle was taken to a blank page after clicking on Get Tickets with his brand new Mac computer using Internet Explorer, I found that I also got a blank page when viewing it with Windows 7 IE and FF. It was only when I re-edited the url to that text link in FF that it now resolves to the appropriate page in Windows 7. However, I continue to get a blank page after clicking on that same text link in XP IE and FF. All these browsers are updated and the cache has been cleared.

Here is one of the two events that I planned to promote today - https://www.facebook.com/events/1382226485375324/. If anyone using XP or Vista Internet Explorer or Firefox can see the registration form after clicking Get Tickets, please let me know.

I already emailed Facebook a couple of times, but this issue remains unresolved.

I don't want to spend my money promoting these events on Facebook unless I know that everyone will be able to click on the Get Tickets link and have access to my registration page.

Is anyone else experiencing similar problems? Is there a known resolution to this problem?
