This part was not changed compared to version 5.8, it just copies some settings filed to the settings folder in AppData.
The message has only appeared in the latest beta. I'll install beta 22.214.171.124. today.
The errors did come back today:
Permissions of the C:\Program Files (x86)\RadioBOSS\Style\(Default).rbstyle file:
Permissions of C:\Users\RadioBOSS\AppData\Roaming\djsoft.net\RadioBOSS_107708674\Style\(Default).rbstyle file
Judging by the frequency of the errors it looks like it's trying to override the default style periodically. What purpose does this serve in the application?
Also separately - we're using 'SouthernFM.rbstyle' I believe - we load our own profile, so I don't know why the default one is trying to be copied across so frequently.
