1. Fro where I'll find only updates to download and update my 4im..1.7.6 to 1.7.7
2. How can I update my existing 1.7.6 virsion
3. I found some forum post url from "ChangeLog Version 1.7.7" and manually update some files by reading that posts. But some other files remain unchanged because there is no link included with ChangeLog. So how can I update my files?
