If you right click on the file( any .dat), then go to properties you will notice a "opens with" and then the program listed...
click on change and change it to whatever you want....
if you want it NOT to use a known program (want windows to ask you what you want to use to open it (like it used to)...
then instead of right clicking on the file.... open my computer (or any thing like my documents ....)
click on tools >> folder options >>
selct the file types tab
in the list that comes up, go find the .dat and DELETE the extension...
windows will now be as clueless as before <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
