Tried installing Tile Sequencer, which I never succeeded. I downloaded Tile Sequencer, put the 'js' file in plugin folder.
All I get is Tile Sequence, cannot create or name a park.
Since then, when I try to open the game I get the message that I've attached below.
Whether I click on yes or no, it will crash.
The only way to open the last park I was working on is to open it up directly from the scenario folder in OpenRCT2 located in documents.
