Hi, I'm getting the following error messages when I launch BIAB or open a file.

Warning: Your current drum kit has no bass drum assigned
Warning: Your current drum kit has no snare drum note assigned
Warning: Your current drum kit has no closed high hat note assigned
Warning: Your current drum kit has no open high hat note assigned

Background: I bought the BIAB 2021 MegaPak for Windows and realized I should have bought the UltraPak for more RealBand content. I downloaded the UP upgrade and installed it but was unsuccessful. (That's a long story made short). So I deleted the MegaPak and all associated PGM files I could find on my computer and then successfully installed the UltraPak upgrade. It now works but I'm getting the warning messages above.

Any suggestions?

Thanks in advance
