If you qualified for an ADR why did you withdraw? Files that are selected to go to ADR instead of a full hearing have a very high chance of being successful and sent back for processing at the VO. Furthermore, once an ADR or full appeal is successful the VO cannot refuse the application for the same reason so for example if your application was refused for the relationship not being genuine, once an appeal is successful the VO can never again say the relationship isn't genuine and must continue processing it. But by reapplying they can deem the relationship not genuine again and again refuse the application. With reapplying you will need to address and correct the reasons for the initial refusal as well as provide new proofs that weren't included in the original application, and not just more of the same proofs. I'm assuming you have your blue book by now and know why the application was refused.
