RTPCR to PCR

One year ago a fellow lab member amplified a cDNA from rat liver mRNA
of approx. 670bp and kept a few of the low amplification bands at -20
in the form of the 'cut out' agarose block following electrophoresis
in TAE. We have just tried to extract the DNA from the gel blocks and
PCR amplify using the same primers and programme (minus RT step) but
without success. Buffer dNTPs MgCl2 and taq are o.k. We've used
Geneclean, BM agarose extraction kit, and centrifugation through
filter paper to isolate some template. Are there any reasons why the
PCR should not work? and is there anything else to try?
Thanks for any suggestions.
