A new magic value probably means a new set of keys to add.

Code:

dwTableSize = dwTotalFiles << 4;

For decrypt table used AES/128/ECB

Ok I have updated the script but the only problem now is the compression algorithm because lzo1x doesn't work.
The following is the link to the script, feel free to test it:

Seems found algo, but one problem - 1 call is virtualized

Edited: See below

It seems a standard algorithm to which have been applied some XORs.
There is xor 0xd7, then there is an interesting xor [ebx] 0x14 and so on.
Anyway it doesn't seem lzo1x.

The OBT was just released two days ago, If someone could get this working again that would be amazing.
