i have sent you the a7 version. a6 and a7 (from 7.05.1 on) need different versions because of the different vertex format of the engine. do you also need it for a6?

you must not load mesh files created with the a6 plugin (maybe you used the a6 demo files?) with the a7 plugin. this will crash.

in lite-c you have to be careful about passing char* instead of the needed STRING*. this can also be a reason for a crash. "" in the source is char* and stupidly won't get converted automatically.

please try if one of these is the reason. i guess so because the plugin works without problems for me and for others.
