Hi I have also encountered the same problem from the start. first time that I tried to open program after initial setup it came up with the warning that it didn't shut down properly and followed instruction to compact the file. It has done this pretty much each time I open it have closed it from the close button and from file and close to see if it made any difference but no. On occasion it wont start at all and closes but I retry and it then works. Have not compacted file since the first time and I am worried that file will be damaged but don't want to go through that carry on each time to use it. Would also like to say have brand new laptop with windows 8 so its a nice clean system. It seems to me a family tree maker problem and annoyed that I have bothered to upgrade if this is what its going to be like and unable to trust it.
