Hi Andrew
Had some health problems so sorry for the delay in replying.

Yes -ZZJAZZ.STY is present see screenshot. I also enclose a screenshot of the warning message that you asked for, plus one showing where I instruct Realband to find the various files, which then generates the warning message. Finally there is sceen capture of the TicketsActivated subdirectory of RealBand

Real Band is installed on my C: drive at c:\Realband. I'm beginning to think that the next step is to uninstall RealBand from C: and start over. Are there any files I should retain from the current install (such as the TicketsActivated subdirectory, or will a new install create all the necessary files from scratch?

Many thanks for your help
Ray
