If it's crash, there are many possible solutions below that may help you.
- You probably downloaded media.pk2 only, full client is necessary if you are using edited databases
- The start area probably have some bugged mobs/npcs
- Start items have some bugged items
- Replace your _AddNewChar procedure with the original one
If non of the above solutions worked [in case you have crash not dc] then use another database, i advise you to use a clean database.
Or trying editing your character position.
