FSOD binary replacement error

Im trying to add some custom items into my rotmg pserver. I have 3 consumables, 1 projectile and 6 equipment. I cant use addition or else i cant go to nexus, so i try to use dat1. I put it in replaced ext="true" with type="(numbers)" then i went to ghostshipCXML and deleted everything inside it and copy pasted my dat1 contents into ghostshipCXML. I recompiled my client then when i open my client it shows a black screen and dosnt load up. Please help!

Why did you delete everything in ghostshipCXML?
