So far, I have discovered that when the error comes up, if I turn the wheel towards me a wee bit, that I can get the machine to resume. LOL, but don't dare stop to trim jump stitches as they occur or it becomes frustrating to say the least!!
Can't answer you 'P' foot problem. I know if you update your software you will loose the hoop forward feature. I have the 11000 and when I had the purchase demo it had this feature. My machine came already upgraded. I have upgraded again to V2 SE as I wanted to quilt. I don't miss the hoop forward as I never had it! BUT I do miss the auto bobbin fill I had on my Elna - that machine had other problems tho and that's another story..... Thats why I have the Janome 11000 - would I go back the an Elna to get auto bobbin fill - NO NO NO NO.
