Let me clarify. After purchasing MJ 7.2 it refused to play any files. Each time I start the program it takes me to the startup window to search for music files. After files are imported it refuses to play any files i get a window that says MJ could not locate these files in the library. I would like to un-install and re-install to see if that would fix it. I am open to suggestions, This is frustarting. The program has not worked well since i first downloaded it. I assume that after I uninstall I will need to restore my license. When Itry to open the .rrg file with my license, windows asks me what program I would like to use to do this. So far notepad has given the best results but there is still some unclear text in the resulting document and I am reticent to un-install if i won't be able to restore my license.
