Installing Spyware Blaster 3.1

I have downloaded the new version. Before installing, it is recommended to uninstall the older version. However, trying to do so I receive the following errormessage:
"Messagesfile C:\ProgramFiles\SpywareBlaster\unins000.msg is missing. Please correct the problem or obtain a new copy of the program".
So I am neither able to uninstall, nor install the newer version !
How can I solve this problem.
Regards

 

I was having the same problem, so I went here: http://www.ursoftware.com/ and downloaded a program called "Your Uninstaller" 2004 (Free trial version, V3.9.516 - The First Drag and uninstall uninstaller). I did n't get any response to my query so I used this program. I think it did the job. I then installed SpywareBlaster V3.1.
