Elisa,
I have just now tested a system with almost identical
setup using pmemd 10.  You must have the "&end" 
where I specified:
run:  MD
 &cntrl
 imin   = 0, irest = 0 , ntx = 1,
 nstlim = 2500000, dt = 0.002,
 ntc = 2 , ntf = 2,
 ntt = 3, gamma_ln = 2.0,
 tempi = 298.0, temp0 =298.0,
 ntb = 1 ,
 ntpr = 250 , ntwx = 250, ntwr = 500 ,
 cut = 9,
 ig = -1
 ioutfm = 1
 nmropt=1,
 ntr=1
 /
 &ewald
 nfft1 = 90,
 nfft2 = 90,
 nfft3 = 90,
 /
 &wt type='DUMPFREQ', istep1=1, /
 &wt type='END' /
DISANG=dist_chi.RST
DUMPAVE=restraint.log
LISTIN=POUT
LISTOUT=POUT
&end
Keep DNA fixed with weak restraints
0.05
RES 1 48
END
END
Please copy and paste that directly and try again.
Reply with any errors.  I can confirm that if I remove
that "&end" I get the same error that you mention.
Good luck,
--Niel
