I follow your guide to the letter and everything goes brilliant until i get to the part following creating the databases.
Now Before You Restore The Database Sql Dumps Go To Your File
"MaNGOS\src\src\bindings\scriptdev2" and Open The Following
This i open as you say but get error at end. 1>ScriptDev2 - 2336 error(s), 0 warning(s). Build: 0 Succeeded, 1 failed, 0 up-to-date, 0 skipped.
What do you need to be able to suggest where i have gone wrong please?
In file mangos/src/src/bindings the file scriptdev2 and its contents now has a green tick on them all.

Also:
Click on mangos then Click on import then Restore from Sql dump as Following :

the Restore From SQL Dump option i do not have. It gives me Execute SQL script... or Import External Data... only.

I would be grateful for your most valued guidance on this please.
