Hi There - What Operating system are you using on your PC? Is it Microsoft XP? If not it could be the problem.

The software was developed in XP and apart from a couple of minor hiccups which are being addressed the SDExplorer is working fine on PCs running XP.

Some users of Windows 98 and ME that I know of have been unable to use the software and it could be that that is also your problem.

I don't know this to be a fact at this stage but would expect that Fred will make some comment as to whether this is correct or not to put you in the picture. Joan
