[AMBER] I/O errors while using CHARMM psf with CHAMBER

Dear amber users,
                           I have been trying to use the CHAMBER utility to
generate an AMBER topology and coordinate files from CHARMM psf and crd.
But everytime I am encountering I/O FORMAT error.

I tested out all the test cases available within the AmberTools suite and
all of them generated the prmtop and inpcrd files within any warnings. The
error is as follows:

PGFIO-F-217/formatted read/unit=20/attempt to read past end of file.
 File name = rna.psf formatted, sequential access record = 988
 In source file psfprm.F90, at line number 2320

The psf and crd files were created using the CHARMM program using the
CHARMM22 force-field. There were no warnings (with bomlev -1), during the
creation of the psf and crd files and I was able to run minimizations
within CHARMM.

It would be really helpful if anyone can help me resolve this. The psf and
crd files for the RNA structure are attached.
