The version number 11.00.04.0200 can be dissected as follows:

> 11 - the major version number (this is what the word 'version' refers to)
> 00 - the minor version number (we typically don't release 'minor versions')
> 04 - this is the Service Pack number for this specific major/minor version.
>0200 - the '02' here indicates 'build #2' of Service Pack 4.

I'm surprised the 'check for updates' doesn't indicate there is a later Service Pack available for your version, as well as a later version (Version 12). I suggest you go to Smart Support and download Service Pack 4. You should also look into why you don't have Version 12 and how you can acquire this.
