Website Trouble

Hey I'm new to this forum, after searching for help I found this forum to be the best spot to ask for it.

Okay my trouble started when I built my own website: www.fatadam.tk

In Mozilla Firefox my website's blog is fully aligned with no errors shown and no horizontal scroll bars

In Internet Explorer my website's blog shows error messages, horizontal scroll bars and the blog's alignment is all out of place.

*please note I'm using That Vista Blog

Does anyone have any suggestions to how I fix this problem?

Thanks for your help it would be greatly appreciated and respected.
