I am sure it's something goofy on my end just haven't been able to figure it out... I have re installed it several times... I have galleys on the front end but all links in Administration panel are blank pages..
Yeah thanks, that worked this time oddly enough... Seems I am always having to do that almost every time I install something huge... Would like to figure out whats causing it... Any ideas or is that normal for large installs of addons?
It's not normal. The master data rebuild is actually using the same code as the post-add-on install code, so there really isn't any reason for one to fail but not the other. In your config.php, you can try setting:
$config['rebuildMaxExecution'] = 5;
This reduces the amount of work done on each page of the rebuild which may help allow it to complete consistently.
