Thank you for you valuable assistance.
I have since downloaded Adobe Premiere Elements 11 and had some degree of
success in that I now can bring up the Welcome Screen.
However when I go on and highlight Video Editor no matter whether I
highlight New Project or Existing Project, all I get is the moving dotted
line and nothing further happens.
However I can get into the Organiser, but no matter how I try I cannot get
onto the Editor Screen.
One thing I did not mention, in both cases I have to use the United States
version on both the disc installation and the downloaded installation
(there does not seem to be a European version or U.K. version) and the
select PAL. for the programme to run in Britain.
As I said the disc was bought from PC World in Britain.
