Tons of driver errors after 2009 SP0 to SP5 install

Running on Vista 32 bit, I get multiple *.dll errors upon opening a file ; "The specified procedure could not be found"

Have tried a modify from control panel without any success.    Any help would be appreciated.

If I uninstall at SP5.0 will I have to release my license and start from square one ?

Thanks
