GMOD Crashes from Archer HPMC's Mass Effect Props

Hiya, I need help with an issue with my Garry’s Mod.

I have recently been having trouble with crashes that seem to be occurring every time I go near Mass Effect props, it immediately crashes my game and sends me to my desktop.
This hasn’t been normal, as roughly a month or so ago, this addon was working perfectly fine with my game.

I can’t think of anyway to solve this issue, so here I am.

Anyone that can assist me on this issue, please post on here with what I can do to fix this.

Thanks

Sorry about this, but I need to bump it.

Bump.

(I hope someone knows how to fix this ;~; )

Bump once again, I might try another site to fix this ;~;
