random error regarding missing files please HELP

[teamblack99]

Some of the media files such as samples could not be loaded

is the error in question. I am using the current version of 11 Live on Windows 10. Typically, missing files would allow you to click orange at bottom and search. There is no orange or option to search. I always collect all and save, not using in samples from a external drive or source. I haven't changed anything and it just started. I have opened this session hundreds of times and changed nothing. Any suggestions?

thanks
