David, apologies for only replying now... wish I had seen yours sooner and not today for the first time...
Don't ever quit as the saying goes! You will be glad you have done what you did, up to the above anyway. I was close to throwing in the towl sefveral times myself. I still feel like that at times, but it is such a super package, and GoDaddy are really not that bad, believe me - the others are not much better, and if they are, they cost more. Paying a little for the next two years compared to paying more over the next two years... hmm, once you know what to do , you do not need to pay more, is my thinking anyway. But if you want to move, then do it for the right reasons, not out of desperation. You can use all your parked domains on this account (presuming you have the deluxe or above account).
I have had success from www.spencerteck.com, and the person who owns it, called John. He is awesome, and has helped me a lot. And doesn't charge, so my suggestion is don't expect immediate response, but he is actually committed to helping out. If you go here, http://www.spencerteck.com/WalkThroughsGuides/tabid/79/Default.aspx you will be able to download the exact step by step [walkthrough] instructions on how to set up the DNN in the root of your GoDaddy account. I have done it, albeit with his assistance wsitht he web.config. It iwll be a good learning curve for you, you will realise how far you have come when you are finished, and the sense of achievement is great. I had the feeling it could be done, but didn't know how. The document on that site will tell you how! And it works, I set up another portal from within DNN on my main account, and voila! there it was, in all its glory. YAY! feel free to contact me off-line if you want to know more, or if you need the documents or whatever.
