Take care, Bill
My master tree is held on Family Historian and in years gone by I frequently uploaded revised GEDCOMs to TP without difficulty. However, the last time I tried it made such a mess (which TP Support were able to fix) that I haven't had the courage to try again. My TP tree is therefore now very out of date! To be fair, I think the problem is with FH rather than TP as I gather they changed their GEDCOM format. My tree has over 10,000 names...
