LE 4 Sample rate problem on startup.

So for whatever reason whenever I go to open up a project file I get the following message as the tracks are loading. “Samplerate could not be set. This may be due to the sampleclock being set to external sync.”

I don’t know why I would be getting this, I’ve not made any changes to the preferences or project settings and up until wednesday of this week it’s been working just fine. Any ideas on some things I might try to get this resolved? Thanks
