SLA Printing Failure

[leeroyxxxx]

Hi Everyone, im new to SLA Printing and ive done the test file a few times and it works every time, im trying to do my own which i have attached a picture of and i keep getting issues with the right arm detaching and Sticking to the FEP. the rest of the model prints lovely but just the right arm. the build supports print but there is a problem with the Supports sticking to the Model. i have changed the depth of the attachment aswell as the thickness of the supports and still nothing will work. do you guys have any tips or hints on what i can do next? xx
