I have upgraded from V8 to 9 on a XP machine, opus starts normally but after a minute or two 2 things happen, one it will display the file names in the old dos format ie only the first 8 letters and all in capital and 2 it will close down by itself and I have to open a new lister, this was not happening in V8 but has started since upgrading to 9.
It's because you are using a pirated copy, I'm afraid.
Idiots like this use the word "upgraded" when, of course, they mean "found a more recent stolen copy"...
lol....
I think you are invited to register your copy
