Blog text huge in Internet Explorer

Hello All,
I have been struggling with a really obnoxious issue. My blog text is massive in Internet Explorer, but not Firefox or Safari (which I run). I can hardly bare to look at it in IE and for visitors to my blog it must look like I am targeting 2 year olds.
So I think it is something screwy in the CSS of the wordpress theme I am using…but what? I ran a CSS validator and it came up with this: Line 194 h1, h1 a, h1 a:hover, h1 a:visited Parse Error [,]
Would that be it? And what does it mean..?

Anyways, here is the path to my CSS:

And the blog for those of you that want to see the Internet Explorer magic:

Any suggestions would be appreciated.

Thanks in advance,
