### Finite modules over non-semisimple group rings, by Cristian D. Gonzalez-Aviles

This is a revised version of preprint 345.
The original version contains errors (Theorems 4.4 and 4.6 are incorrect). I am deeply grateful to Jon F. Carlson for pointing out the
errors. Further, I apologize to those readers who may have been led astray by these false statements. In this new version we have
corrected the errors. It turns out that the original wrong statements referred to above ARE correct for all finite cyclic groups (as well as certain
types of finite non-abelian groups), which means that most of the results of the paper are correct as originally stated.
