[gmx-users] Error in pdb2gmx

Hello there,
I am trying to run pdb2gmx on 3bzu.pdb file and got the following error

Opening library file /usr/share/gromacs/top/ffG43b1.rtp
Opening library file /usr/share/gromacs/top/aminoacids.dat

-------------------------------------------------------
Program pdb2gmx, VERSION 3.3.3
Source code file: pdb2gmx.c, line: 878

Fatal error:
Chain identifier 'A' was used in two non-sequential blocks (residue 1034,
atom 7961)
-------------------------------------------------------
 as I am new to this field. I'm finding it very difficult to find the reason
and rectify it.
Any suggestion would be of great help......

With Thanx,
Vivek
