Welcome.

Reflash the stock ROM and leave well alone. Rooting can be risky.

CF Autoroot doesn't root all ROMs (it's the ROM that gets rooted, not the phone hardware). Make certain that your phone, using the ROM that's in it, is listed on CF's list of ROMs it roots. Then, as Belodion said, reflash the stock ROM (you'll lose all your data and all your downloaded apps, so back everything up) and try again with a version of CF that does root that ROM.
