Dragon Age Origins? help

hello, I'm looking for help on how to to use the dragon age toolset.  I bought and beat Dragon Age Origins on steam and then I was told about the tool set and wow I love it.  I have tried some mods from Nexusmods website and some from bioware but they kept crashing my new game or i would have to keep deleting my inventory and that sucks so I was lucky enough to come to  a website blog by John Vanderbeck want to give credit to who it be longs to.  Following his blog I was able to some how get one item in my game and I was so excited for a day but then I couldn't get another to spawn in my game and I don't know what I'm doing wrong?  I know the first item was luck,  I keep getting a warning "No starting area specified for campaign"  So if anyone has used or is using DAO toolset please help lol 

I don't want to do any thing big, I would just like to make my own weapons and armor to make the game a little more exciting for me.  It was so cool to have my player run through darkspawn with a weapon I made.  

I appreciate any help Thanks
