orcad problems in layout and shematic

[Tom2]

I did a pcb with orcad and i get the following message:

In layout :
The first time which i try to choose the footprint i did a mistake and after this, each time which i load the netlist.mnl i get the same message. (I tried to recreate a new netlist, i copy the shematic to another project .... but the error is not able to correct).

AutoECO Error Report
FILE-A: C:\ORCAD\ORCAD_16.0\TOOLS\LAYOUT\DATA\_DEFAULT.TCH
FILE-B: C:\ORCAD_DATA\test.MNL
ERROR: Component U2 (with fp SIP/TM/L.200/2_U2) has no pin 3
1 error found


In shematic i have the following warning (in DRC process) i don't know if i must ignore these warning? :

Dear Sir,

In ref U2 components don't have pin 3. But in your may connected in pin 3. Check that component connection. Give appropriate footprint.

Reason for unconnected net:
*) May connection given by line. Line no meaning in the circuit. use wire for connection
*) May connection not be in the grid.Use grid during working in the schematics.
*) May that component was not having connection. Give the nc connection.
