im getting the same problem. Havent played in like 2 months, booted up mopar, told me I was doing a "first time download" then it gives an error after downloading.
"Sorry an error has occured, whistle loading Moaprscape.
1. Try closing ALL open web browser windows.
2. Clearing cache
3. Different game world
5. Selecting different java."
All options to helping, none helped. If the server went to 1.8.131 Java, I cannot download. =\
