As mentioned sometimes the mods fail to load.
There are many ways to load mods. Please describe the process that you've used to setup and/or load the mods, so that we can better understand what's going wrong.
Also: please try to run the game via the
Flash Player Projector content debugger instead of the regular Flash Player Projector. If the game encounters an exception then it will show a popup error message, which you can copy-paste. That message will help us to understand what's going wrong.
Also do you need to include the as3 compiler in the file?
No, you don't need to do anything with the AS files or with the compiler. Source code is provided as a bonus for apprentice modders. If you aren't a programmer then you can ignore (or delete) those files. Please note that many of the TXT files are actually important; they contain Settings and some mods will not work properly if they're lost, renamed, or moved. Please don't delete TXT files unless you know what you're doing.
