Replaced remove() with ent_remove(), but also having problem with walljump and ledge grabbing/climbing after updating GStudio to A6.40.5

Tried checking the syntax and found error on line 375 in level1.wdl in the 2D Movement Script.
Error(50): Parameter unknown c_move_x Parameter.
Now i'm not really expert c-script programmer. However it would be nice if someone who is and has already fixed these problems, could give me a little hint about the error and why it isn't working. So I can learn from it and try to fix myself.
All the best,
Dusty
