First you have to match the name of molecule in both files, in your pdb
file the name of molecule is TAR while in toppar file it is MOLECU, so
change it to TAR to match.
Second split toppar.txt to top.txt and par.txt then in top.txt rename all
atoms in third column to C , O, H, ....etc. VMD can't read these atom types
(for example change CG2R61 to C, HGR61 to H, OG2D2 to O, etc) but when psf
file is generated you have to return these names to the original.
Just do these editing stuff and it will work.
