Hello Kapeesh, I'm sorry to hear that you're having issues with adding the Curse of Strahd Module to a new game.  I have created a new game and was able to add it. As such,  please carefully work through the following steps of our guide to  Solving Technical Issues  to rule out possible causes: Step 1: Make sure to use the right browser Please check if these issues persist when using both Chrome  and  Firefox. Step 2: Ensure that there are no extensions/addons interfering with Roll20 Please disable  all  add-ons/extensions. Step 3: Clear your cache If none of the above succeeds, please thoroughly work through all of the requested information in  Step 4 .  (Don't forget the complete Console Log!) Thank you!
