Minor bug fix version released. Download link in first post. This fixes all the issues reported till now.
I checked the file you uploaded. The offset data was corrupted and that was the cause of the crash. The same data is present in two places in the file so I guess the game ran fine because it reads the other set of data.BUG : first time i opened global.texpack it opened i clicked a texture inside it gave a error "Bad Allocation" from now on it gives this error even on opening global .texpack
