I purchased an Ejukebox licence on the 5/1/10 and all seemed well, however yesterday when I clicked on the icon to launch the program all that keeps coming up is a box telling me my trial has expired and asking me to register..please help

click Register Now! on the startup screen and enter your email password, click 'License is Full' and then 'Remove License' next to the dead install. Now 'Use License'!

Hi many thanks, have done this but when I now launch ejukebox message flashes on screen Error copying files and just stays there.

re: error copying files.. i am not sure how you could get that - if the error says anything more specific please post it here
also make sure you are running your install from C:EJukeboxejukebox.exe
If not then download and run full install from http://audiosoft.net/download.htm
