Installed Mint 17 KDE and Libreoffice crashed upon startup

Error message started it couldn’t create a file. So I attempted to start Libreoffice as root and it started fine and exited fine. Now when attempting to start Libreoffice as user it has different error msg, namely it thinks root is still running soffice, even after computer reboot. However, if “continue” is selected Libreoffice does start and works fine. Question: what can I do such starting Libreoffice as user does not result in the error msg stating root is still running soffice? Thanks, Earl

Only a hint: Ask also your question in the Linux Mint Forum. Generally you can get good answers there especially if it is Mint related. Although your question appears to me as a Mint topic,you might get a helpful answer here as well.
