What are your computer specs?
Have you been able to open the route before?
Since you've crashed to the desktop, I recommend running a database repair (DBR).
At the Launcher, click on Developer on the menu bar and choose Repair database.
If that doesn't work, try an Extended Database Repair (EDBR) by holding down the CTRL key while choosing the same. This can take a bit longer.
When either repair is complete, check for faulty assets. If there are any faulty assets, highlight them and right-click on them and choose view errors and warnings. The errors should show zero, warnings are sometimes still there. To clear the display completely, exit from that view and then check again. There should be none. If there are any, you need to repair or replace the assets.
Hopefully you have a backup in case the route is stuffed and needs to be restored.
