well, I did it...
I uninstalled sh4 from the pc (that is, I removed via uninstall), erased the sh4 folder in the my documents, checked to see all removed in the registry (but I didnt touch the other copies I had stashed all over the hard disks)
rebooted, installed sh4, new reboot, made a run of the program and then I found I didnt have patch 1.4... downloaded that. installed it. once more reboot, now I made two copies of the sh4 ver1.4 folder..... ran multish4 and jgsme on them and installded FOTRS on one of them, keep the other as a clean v1.4 install.
made a quick run over pearl, looks nice.
tonight i will put UBM back in the main program files.
one other thing... all the installs copied of op mosun, tmo+rsrd etc are fully functional.... thank God.
will give FOTRS another try.. for first mission Im going to ::::::::::: and :::::::::: in ::::::::::: soory, why ruin the surprise.
