Did as suggested, used up my last download (although I have a record of only one previous download) re-installed as described, exactly the same result now I know nothing of your code or modelling but I could use a bit of help particularly as the product is not on the cheap side there is nowhere else to ask for help . I have no other plug-ins I guess you can wash your hands of it and that just leaves me $43,00 poorer and aggravated, or you who know your code and your product could at least suggest where I could start looking for a solution, I'll put my time in, but without your help I don't even know where to start
