were 2014 and 2015 already installed, if you reinstalled them, it may not matter 2014 and 2015 versions cannot be updated and are no longer supported. the crash may be due to the states no longer being available or some issue with the OS. so were you to open the tax files with the reinstalled apps you would likely change the returns from what was filed
if you have the 2014 and 2015 tax files, at your own risk, because Turbotax does not support using them, you can email the file to Taxprinters.com and for a fee they print out the federal and if requested state returns
