Omen Missing from UI

[Malzand]

Ok, i'm not a total noob about installing UI's having tried plenty and finally deciding on the best looking and functional one

I have just done a complete clean install of nUI and installed some additional addons i use all the time

• Auctioneer
• Postal
• Bagon
• Carbonite
• Lightheaded
• TomTom
• Smartbuff
• Omen3
• Ratingbuster

I added Omen (fresh download from curse) but i cannot get the omen window to appear in nUI (i swapped back to an old interface and then the default one and it works there). The omen config window will openin nUI and all options are available but even using the slash commands (/omen center, /omen Show) i cannot get the omen window to appear anywhere!

Are the addons i have added conflicting with nUI? have i done something stupid?
