Track Path is Missing

[big daddy]

I make a custom disk with Microstudio then import to Hoster from disk. ZThat way we have a disk as backup just in case. This is happening on two different Laptops with different external hard drive and they also have backup hard drives which I have tried. It also does on desktop I use for testing with internal hard drive. May have found problem not sure yet, still testing. I went to re import disk from 300 up and noticed that most of them are PHM or PHN and I had them listed like this PHN00706-307 and all the rest before 300 were listed like this PHM0302-249, maybe that extra 0 makes a difference or maybe just a problem when imported. Reimported through 307 then just changed 308 - 314 deleting the 0. So far seems to be working. I will try to copy files to other computer and test. Let you know.
