You lack the required entitlement to start dime-skills
Explanation of what that means:
All Dime Studio assets use the FiveM escrow system, which means scripts are linked to your FiveM account (the account you used on Tebex).
In order to work, the asset/s must be run in a server which is using a server key created by the same FiveM account you used on Tebex. You can create a server key in FiveM Keymaster.
