Thanks for your suggestion. When I tried it I had the following error:-
Loadlibrary failed ,specfic module could not be found.
However,I tried a reinstallation of the Mp3 Utilites and this time it installed but when I tried to open the AMV Convertor, the hour glass appeared for a few seconds and nothing more. When it came to shutting down the End Program for AMV convertor showed. I clicked end now but windows would not shut down and I had to hold down the off switch to shut the PC down.
This repeated the next time I tried to open the AMV convertor.
A further time I tried to open AMV convertor and left it to work on another PC and after about 15 minutes woe and behold the AMV convertor had loaded and was working, but after closing the program again I was unable to shut down windows in the normal way.
Apart from re-formatting any ideas?
