Ive seen a few Mach 3 machines stop working in the last few months.
 It seems  after the computer downloaded an update then Mach3 would crash every time it was run.  Installing a fresh win7-32 and not letting it do an update was the only  way to get it working. 

Anyone else have this problem ? Is there a fix ?

There are a few threads on the subject, this one, I think, explains the issue; http://www.machsupport.com/forum/index.php/topic,38014.msg258239.html#msg258239
