I have now installed the BIAB on my new second PC when playing an * .MGU file are not played back as usual as on my first PC, all real track channels (green color) BASS, drums, piano, guitars. On my 2nd PC, only the real track drums and bass will play back. All other channels are mute!

My guess is your MGU file is slightly corrupt. There are three things you may want to try.
Thing 2: Save the existing song file under a new name (for example Song.MGU to Song01.MGU). Close BiaB. Open BiaB. Load the new name song file. Generate and play. Does the new name song file play correctly?
Thing 3: Open RealBand. Press F3. Load the new song file. Go to "File" > "Save As" and save the song file under a new name for a second time (for example Song01.MGU is saved as Song02.MGU). Close RealBand. Load the new name song file (Song02.MGU in this example) in Band-in-a-Box. Generate and play. Does the new name song file play correctly?
hello Jim, thanks for the info, I only have BIAB 2020 / Vers.734. But since this problem is with all the songs that I load to this PC (AMD Ryzen), I think that this problem may be due to the software that is not coordinated with this hardware, everything runs wonderfully on my 2 other Intel PCs.
On the advice of support, I uninstalled BIAB 2020 and deleted all files. BIAB 2019 installed, and BIAB 2020 installed over it. Now everything is running like clockwork! All realtracks are now played!
(I can still remember, with the first faulty installation, there were two error messages that I acknowledged and I thought nothing of it)
So always watch out during the installation, whether there are any error messages, because then you have to be prepared that something is not working.
