Your issues are caused by having old maps with a latest 3.0, there’s a known incompatibility.
Take a look at this guide to resolve the issue by installing the latest maps for 3.0 → Sync 3.0.20204/23219 with EU 2.21 (F11) or EU 2.22 (F12) or EU 2.23 (F13)/EU 2.24 (F14) Map Installation
You could try that as well, but I think it’s best for you to just update maps and stay at the most current Sync3 3.0 build.
