NSW Express cleanup & one button checkup stopped working

Hi,

My OS is Windows Vista Home Basic x34 with istalled (NOT pre-installed) NIS 2010 and NSW Premier 2009 (Version: 12.0.1 Build: 1)  

 

Until recently could run with no probs NSW Express cleanup & one button checkup but from today both apps stopped working and kept getting the following Windows error message: "express cleanup stopped working" and a similar for one button checkup utility.  

 

Run NSW windoctor (no problem with this utility) but to no avail. Uninstalled & re-installed NSW, cleared the registry from NSW traces but, the issue is still there. Any ideas how I could work my head around this?

Thanks
