Help to solve the precomp error.

[Alash Als]

This error also happened with me... In this check if you used any zlib streams of other file or you had used any unexpected method...
There are some files which can not be processed by precomp(example:files of saint's row 4)
If they are processed through precomp, the'll now get their sized increased so that you can recompress the file.....
Again some files can not be highly compressed without processing through precomp
(example:GTA 4 files)...

Check what type of file you have selected to compress.....
Again some files which cannot be processed through precomp, Can be highly compressed using only srep+lzma(example: Files of Hitman Absolution)

So if precomp cannot be used compress the file, then use
-msrep+rep:130mb+dict+delta+lzma:a1:mfbt4:d256m:fb1 28:mc1000:lc8
