Help...in a hotel and can't log on...runtime error

Good morning folks, I did the READ ME etc yesterday. My family is currently in a hotel saving for a home again, we lost ours when I lost my last job. I had no trouble signing in to the hotels internet service until yesterday, after I went through the "READ ME etc" items. Now I can't get it to even take the password, as soon as I click on it, the runtime error box pops up. I'm at work now, but really need access there. My OS is Windows XP. Can anyone help in the next few hours? Thanks, really, really thanks.
