  It has been shown that four dimensional N=2 gauge theories, softly broken to
N=1 by a superpotential term, can accommodate metastable non-supersymmetric
vacua in their moduli space. We study the SU(2) theory at high temperatures in
order to determine whether a cooling universe settles in the metastable vacuum
at zero temperature. We show that the corrections to the free energy because of
the BPS dyons are such that may destroy the existence of the metastable vacuum
at high temperatures. Nevertheless we demonstrate the universe can settle in
the metastable vacuum, provided that the following two conditions are hold:
first the superpotential term is not arbitrarily small in comparison to the
strong coupling scale of the gauge theory, and second the metastable vacuum
lies in the strongly coupled region of the moduli space.
