Hex on Steroids 0.5 Error

when I load my profiles on hex on steroids and I try to open the tunedata.iff file, the Hex on Steroids encounters a critical error

if we are going to be able to help you, we need more information. If it mentions a txt file, we need to know the error in that file too.

Did you remember to decompress the iff file before opening it?

i got the same error, how do you decompress the iff file? BTW here is the txt file that was created when the error occured.

System.IO.EndOfStreamException: End of stream reached with 4 byte left to read.

None

open it in the 2Kx Mod Tool to decompress the file.

I tried using Nba2KX tool but when i open up tunedata.iff, it asks me if i want to decompress, when i hit yes, its gives me an error of "java.lang.ArrayIndexOutOfBoundsException: 2016"

i have the same issue here with Hex on Steroids....help needed
