This works well and is a fast approach to the issue, if you'd prefer a more permanent solution you can use the following steps:
1) Install the .swf RotMG client, both .exe versions won't work for this.
2) Install jpexs flash decompiler from: https://******.com/jindrapetrik/jpex...piler/releases
3) Open the .swf file in the decompiler.
4)Go to scripts>kabam>rotmg>messaging>impl>GameServerConne ctionConcrete.as and replace both instances of "1.0.0.0" to "1.0.1.0" in the P-code source.
5)Go to scripts>com>>company>assembleegameclient>parameter s>Parameters.as and replace the single instance of "1.0.0.0" to "1.0.1.0" in the P-code source.
6)Save and overwrite the current .swf hacked client file.
7) Open the .swf file in flash projector and it should be working again as normal.
