I really appreciate your insight into this problem - I did have a look at
the Lipidbook
website and downloaded a new lipid bilayer from there. I followed the same
and now an error regarding my topology syntax has appeared:

Fatal error:

Syntax error - File topol_popg.top, line 10

Last line read:

'#include “gromos53a6_atb_popg.ff/forcefield.itp”'

This is what my topology file looks like -

; Include chain topologies
#include “gromos53a6_atb_popg.ff/forcefield.itp”
#include “popg_after40ns.itp”

; Include water topology
#include "gromos53a6_atb_popg.ff/spc.itp"

; Include ion topologies
#include "gromos53a6_atb_popg.ff/ions.itp"

; System specifications
[ system ]
128-Lipid POPG Bilayer

[ molecules ]
; molecule name nr.
DPO 128
SOL 3,527
NA+ 128

I was hoping you might be able to advise me on resolving this issue.
