Hi,

i used RCB a while ago, but deactivaed it for testing purposes. Now i wanted to reactivate. But even after a reboot it showed an Error if i try to start:
Unhandled exception occured during execution of RCB:
'NoneType' object has no attribute 'find'
See xbmc.log for details

The file kodi.log shows the folloging (just the last few lines):

OS: Windows 10
Kodi: 18.4
RCB: 2.2.3

Any ideas?
Thanks in advance :)

Ok, i found a solution: today i did the update to Kodi 18.5, after that i deleted the whole directory
C:\Users[username]\AppData\Roaming\Kodi\userdata\addon_data\script.games.rom.collection.browser
and configured the AddOn from scratch.
There are still RCB-related Errors in the Log-File and Kodi crashes if i try to quit, but the RCB itself is working (for now).
