When my WB 3.50a "expired" and I used CM to DL 3.51, only to be told that to install 3.51 I had to use SDC which as you can imagine only showed 3.50a updated to today, I was a bit bewildered. But then when I discovered WB 3.50a and 3.51 in two different folders, I uninstalled them, and even had to drag one out and into the trash by hand as there was no uninstall file. Next thing I did was run WinCleaner from BLCorp.com and cleaned out all the useless dll's and then the registry. I rebooted, came online, cranked up SDC and there was WB 3.51. as if by magic. I DLed it and installed while online and bingo, everything worked right as rain.
I simply guessed my way through the whole thing.
I use Windows ME.
