Paste as a block problem

I had the old version of draftsite which had the "paste as a block" problem where you could copy and paste one block ok but it wouldn't allow you to paste any subsequent blocks, This was solved in Version V IR3.1 64. which I used ok for several months. During a windows automatic update my computer reset while draftsite was open, draftsite worked but I had one or two problems so I uninstalled it, took of the directories that are left on the computer to give it a fresh install. Everything works ok now apart from the "paste as a block" command it randomly pastes any block that exists in the drawing. This seriously slows me down and I have to make blocks using the block command, any ideas?

Thanks.
