What model cuberevo you have? For me IP9000 is best latest PGI1.4 For installing first make factory reset and then install first original soft (cuberevo.r13791) and then PGI version. Check that you have right version for you model. Easyst way is use USB stick. How to do is in manual or you find it fom internet. What it mean you not find channels ? have you made satellite settings and correct fec in database?
