Guide Data Corrupted > ChannelsDVR unreachable (Seedbox)

[osk3]

Hi
I tried to upload a .m3u file in the XMLTV field by mistake and suddenly I am unable to access the web portal:

http://dvr-seedbox.com:8089

Is there anything I can do to get access back?
I have tried restarting the service and rebooting server but seems to do nothing.

Also tried deleting the .airings and .groups folders as suggested on the question below but still no luck:

Windows - Server Crashes on Startup

looks like around 10 AM this morning the server had an issue updating guide database. That ended with a "panic: runtime error: index out of range [2500] with length 2500" I didn't notice it until around 2 PM at which point I tried to start it again and it crashes every time on startup. Copied what I assumed to be relevant logs below.

Any help appreciated
