This is my 1st post here, and have a bit of trouble with my player. I have a Sony Walkman MZ-NE410 player, and have never had a problem until recently. When I load my music in,the window to change from lp2 to lp4 doesn't allow me to change, and the record button doesn't light up to highlight it, so I obviously cannot record anything. I got an error message in the midle of recording the other day that said recording failed, or something like that.I have uninstalled and re-installed the Sonic Stage software several times, with2 different installation discs, but to no avail.Any suggestions? I had a problem with the latch on the player last week, but am still able to close it.Would that have any effect on the recording process??Thanks....
