thanks god
after alot of searching and reading in this great forum I could upgrade my receiver, it is digitall world (SFT-5010).
I worked all last night to know how to set my COMS port, finally it works.
but i still need ur support because I'm still in the beginning (no experience), after upgrading my receiver I set it factory sitting then i install all hotbird channels TPS, Multivision and ABsat, unfortunately they are still not working. is there any keys or software need to be installed also in my receiver. please advice in detail.
thanks aolt for ur support
