Gmod CoderHire Addons Conflicting!!!

Basically I have MANY addons I have bought off coderhire and if I add any more addons like the stacker tool or some really expensive addons off coderhire that need to be put on the server they just break everything

For example if I added something off coderhire like this “http://coderhire.com/browse/script/648/payday-2-style-bank-robbing” 90% of my tools will disappear and most of the ones that are still there don’t work

If I even try to add simple entity’s like a vending machine all my tools will break

95% of my guns are called “Print Name” besides my phys gun

And I just do not know what to do because nobody on coderhire will help me or refund me for that matter so it’s up to you guys to help me!
