I have made a great website with xara webdesigner 10 and now ik hear from my hosting provider that my site works with ASP 1.1

I need to change my website to a higher version of minimum 2.0. For me this info is like learning chineese.

Can somebody explain me what to do ? I bought the xara upgrade 11 premium. Will this help or do i have to do other things ?

Thx
