My DraftSight program shuts down immediately upon start up. There is a message in the bottom text field reading "Unable to open file. Please attempt File>Recover." I have already attempted to repair the program as well as uninstall/re-install the program several times. I use this program every day for work, and I would really appreciate if someone could contact me ASAP. I have my mobile phone number and email listed below. Thank you so much,
