That is strange - I am using A7 lite-C. My code is compiling from a .c file. There is no wdl file in the game directory.

I have run it with a shorter name and no longer get the "Invalid name: sub_prototype_test_2.wdl" error, but it still has the other errors when I execute the compiled game:
t_day_sky+6.TGA: Can't open file
WAVEMODEL_NEAR.MDL: Can't open file
WAVEMODEL_MID.MDL: Can't open file
WAVEMODEL_MID.MDL: Can't open file
