I am still on Jriver26, although purchased the option for 27.
I recently ran out of room on my 2 TB hard drive E: where I have my music, which was my oldest hard drive, so rotated a newer 4 TB hard drive F: from backup to my regular hard drive and purchased a new drive for backups.
I was not able to make a new library for this, even after reading the directions, (I need a JRiver for Dummies), I cleared my old library, and then imported the F:music file into the library.
Some of the files did not get added properly, like it was not reading all the metadata, so while most of the files were fine, a few albums had some unassigned and some were correct, such as track 2 and 3 of Joni Mitchell's Don Juan's Reckless Daughter, show up correctly with the metadata, and all the other tracks are unassigned, even when they are listed on the data files, and put in an unassigned album.
Today I ripped several new CDs, on another machine, as JRiver also does not recognize a file path for the CD to be ripped on this machine (a Dell Latitude 5530 running Windows 10) ever since I upgraded to 26 from 25.
These files, on my external hard drive, all went to the unassigned album, even though I did the same process that worked in the past, only difference was an updated Jriver26, and I did fill in the data prior to ripping the CDs. So problems ripping to JRiver started on this computer earlier, and now no metadata.
Also, a new playlist I made, had some songs get cut off early. Is this something with the Library path, that I can fix? Or are the computer drivers getting old and dysfunctional?
