I edited your post and moved it to the tech support area of the forums. If the game is freezing/crashing, be sure to check the minimum requirements here to make sure your system at least meets the minimums. Most issues can be resolved by uninstalling/reinstalling the game. The steps to do that can be found here. If the freezing continues, please reach out to our support team by clicking the link in my signature, selecting the PTCGO option, and then selecting "Contact Us". Hope that helps!
