I fear pro5 is no longer around to update this (which is a 2014 release) but perhaps updating the .tp2 to be compatible with 1.22 is a simple enough operation?
Yes, it is.
1 line need to be updated :
REQUIRE_PREDICATE MOD_IS_INSTALLED "setup-bgtmusic.tp2" "2" ~BGTMusic component 2 is not installed, SONGLIST.2DA is missing required BGT/BGII song entries~
