Problems with IE

[judeabb]

I designed the following site using CMSMS - http://www.sidmouthfolkweek.co.uk
Some users (not many) who use IE aren't able to view it properly. The main content is squeezed to the bottom of the page - after where the side columns end. I assumed it must be a CSS issue and have tweaked but to no avail. Trouble is it works fine on all the computers and browsers in my house so I'm a bit stumped. I'm attaching the CSS file and if anybody's got any ideas what's causing this I'd really appreciate it.

Thanks in advance.

Maybe you want to check it first with validator and fixes those issues, sometimes clean code is all you need

Your CSS says 1000px width on pagewrapper but the template tells IE to use 750px...
