MadDog, I have already done that to no avail. I first reported this issue back under version 9. Several others have reported the same problem. One person said they can duplicate the problem at will based on the existence of a specific RM file. RM has indirectly admitted the problem exists, but so far, it has not been addressed.
Just installed the 10.0.4 update and tried to download a tree from Ancestry. Something has changed, but it still fails. It immediately says 100% with the first step highlighted and then locks the program requiring a force quit to exit RM.
Just installed the 10.0.5 update and tried to download a tree from Ancestry. Same issue as 10.0.4 and it still fails. It immediately says 100% with the first step highlighted and then locks the program requiring a force quit to exit RM.
