Reinstall or Deinstall

I am finding that a lot of functions in my DB2 database do not work. Much of this is due to the fact that my Windows account is not a member of the DB2 windows groups. And I can't change this since I do not administer the Windows accounts on the domain. My short term plan is to reinstall DB2, and opt not to use Microsoft Windows groups to manage DB2 permissions.

On a sad note, I might even just uninstall the whole DB2 database from my machine. Previously I had received notification that I was going to transfer to a project at work that used DB2 exclusively. Today I found out that this transfer is not guaranteed. Apparently I need to go back and interview with the team to see if I can get a position.
