I just installed iTunes 4.5.1 with no problem. I then installed the iPod update with no problem....except that iTunes no longer recognizes my iPod.<br>It shows up on the desktop and is recognized as a hard drive and even starts iTunes when upon restart. The two choices (whether to erase and upgrade or keep the library in place) were greyed out and it keeps telling me to plug in my iPod. Yes, I have tried all the combinations of plugging and unplugging.<br>If nobody else has the same problem, I will have to retrace my install steps. <br>I will not panic...........I will not panic.............yet.<br>
