Hello - Before uninstalling and starting over, try to update to the current version of NI-DAQ: <a href="http://digital.ni.com/softlib.nsf/websearch/C1F802E457EA042586256DD00001B0C9?opendocument&node=132060_US";>NI-DAQ 7.1</a>
Also, make sure you are explicitly saving the properties and/or tasks you are creating. Hopefully, this will fix your problem. There are not any known issues at this time and there is no reason to revert back to older software. Please let me know if this helps. Have a great day! Becky B.
