GRF Editor (Failed to decompress data.)

[Technoken]

Can anyone help me about GRF editor? I'm having this error when I'm using GRF editor. I successfully decrypt my grf, but whenever I try to extract the files or even click to view the files it's always throwing up an error

Btw i'm using GRF editor 1.8.0. I also used this to encrypt this GRF. Decrypting the grf works well before and I can change the datafiles in it. But now IDK what actually happened why this error started showing.

Is there anyway to save my data files? I'm actually frustrated right now coz I don't have any backup of this GRF data files.  

EDIT:

IDK what happened but it seems  working now. But still there are times that the grf editor is saying the same error. What I did is grab another copy of my grf and try to decrypt it again and somehow it works.

You should open a new thread/question, as this is from 2017. Anyway, it simply means the entry is corrupted or encrypted, most likely encrypted.

Well since you have a copy,  make a back up while you can.   You can always try using a different version of grf editor to see if your results change.
