PranQster: Sorry you are having all this trouble.
Please post the dates and times of the map, proc, cm, and aas32 files that are in doom3\builders_influence\builders_influence.pk4\maps. If you have extracted these do not look at those but look in the actual pk4.
Then repeat for the above extracted files if you have extracted them.
The map file should be dated 18 March and the others 23 March. Please confirm. If so, then clearly they are not out of date and there is some other problem beyond my knowledge.
[EDIT] I confirm both mirrors were updated.
Here are the dates & times... they do not get changed when I extract the maps from the .pk4, so it was easier to do ls on them:
