Files stop loading during a mix

Files stop loading during a mix
I have recently started having this issue with Cross 3.3.10 where during a mix files seem to stop loading. This problem appears to happen after I have been mixing for around an hour and escalates in 2 stages,
1st - when I try and load a file it will say that the file is loaded however it will not play; so I will have to load another file and then reload the initial file and after a wile it may play (however this does not always work and after doing this a few times, more and more files stop playing and then the second stage of the issue occurs).
2nd-The second stage is that after loading/ attempting to load a few tracks this way, mixvibes will just get stuck continuously attempting to unsuccessfully load a single track to the extant where I cannot drop any other file into either player.
Once I close and restart mixvibes everything is all good again, but this really interrupts the flow of the mix when recording/playing out ect
Any ideas or help would be really appreciated
