Ok so i rented lego rock band hoping to export the tracks to rb3. but i find out the code has already been used. So this is what i dont understand. Why is the code given with game only able to use once. If they allowed us to use the code multiple times and give a unique code from the other one to be used once they would increase their number of sales on exports. which in the end gives them more money. There must be lots of people out there who tried this and said F*%$ this after realizing this problem. Harmonix you lost my ten bucks now. Im not buy this game only for the export.
