i can see you used optimal 
in that case throw the data1.bin to my unpacking session you can get that from my thread
it will unpack it, there is only one reason why this will not unpack, it may gave error when packing then ignored the error and compressed regardless :/ try to compress again if you feel uncertain and always check if the compressed file is decompressable before deleting the original
