Playback error - fails to connect

Hi NT8 team,
I have used playback with no issues in the past but just a few moments ago when i tried to log into playback connection, it throws the exception you can see in the attached image. Please advice of a resolution. Thank you.

I found the error. I had created a dupicate replay file with a non-conventional replay file name. I removed it and all is good.

Kashter, you mean this. Refer to attachment.

DO NOT rename/create/copy files in any of the sub directories in Replay folder(C:\Users\ABCUser\Documents\NinjaTrader 8\db\replay).
You think by creating different file names it will not be used, well the program checks all filenames must be in the correct format before it starts.
Therefore if you DO create them, the file must be in this correct format yyyymmdd.nrd otherwise you get these errors:
