Problem with new release of MatLab

I just installed MatLab 2008a and ran a dynare program that worked on an earlier version of Matlab. I got this error message

Invalid MEX-file ‘C:\workOld\dynare3\Dynare3.065\dynare_v3\matlab\gensylv.dll’: The specified procedure could not be found.

Can anyone help?
Thanks.

DLLs compiled with older versions of Matlab aren’t compatible with newer versions.

We have fixed the problem in Dynare version 4 by providing DLLs in a directory structure by computer architecture and versions of Matlab. We will not do the same thing for Dynare version 3.

My recommandation is to switch to Dynare version 4 and and nag us until we provide the last few features that are present in version 3 and not in version 4

If you really want to solve the problem for Dynare version 3, download version 4 and copy the relevant DLLs from ./dynare_v4/mex/2007b

Best
