Must be a fault with disc I'm not sure what to recommend maybe they need to replace or refund you.
I'd say it's what the corporate board decide to go with from a business perspective.
Following themes is a solid business and marketing sales strategy.
I'd recommend using bricklink or lego.com I know it isn't the same experience.
Try updating the game or checking the disc.
You can probably pick up a cheap copy from eBay or steam.
Spyrius and castle/ kingdoms
Here's one idea find out what the parts are and try to get them from bricklink or eBay bundles then build it yourself if you can get the instructions.
I miss the rock raiders sets also the Spyrius sets they were awesome.
Skitarii guard armed with transonic blade weapons.
I'd be interested in the new parts and how I can apply them to my MOC's there's bound to be some new pieces of they start a new product line.
