Lost IMEI AFTER ROOTING

[alex1236x 0]

Hi everyone, i'm kind of new to this. My phone wouldn't go on anymore so my last option was to root it. I rooted it using Paul's stock rom :

Now the phone works great, but the only thing is that there is no service, and it seems that my IMEI has been deleted. When i dial *#06# the letters IMEI appear but there are no numbers, could anyone help me out with this ?
