Looks like a false alarm. Managed to figure out to start digging the radio London folder based on the figure of progress bar and I found a faulty events.ini file. Removed it and and ran your tool. Everything ok!
I apologize this mess
Damn, now I'm both, happy and embarassed hippie!
Edit:
Seems like there's some sort of problem with BBC station from Multi Station V2 events.ini file and with this tool. Confirmation would be great
