Unable to import cds after installing iTunes latest version 10.1.0.56

Question

I downloaded iTunes 10.1.56 after having problems with the 10.1.0.54 version. I can only download the first 1/2 of song 1 and nothing from the rest of any cd. Under "time" for each song, my library says "Not available". When I click on it to listen it gets skipped over until a previously imported song comes up. Same thing happened with the previous version as well.
I ran diagnostics and here's the results. (It also says I'm not the Administrator but I am so that's confusing.)

many thanks, Lucky.
There doesn't look to be any newer versions of Dell firmware for your DVD-ROM GDRH10N. It might be worth heading to Windows update and checking to see if there's a firmware update for that in your optional hardware updates.
Otherwise, head to the following page at Dell:
[Drivers & Downloads for Dimension E521|http://support.dell.com/support/downloads/driverslist.aspx?os=WLH&catid=-1 &dateid=-1&impid=-1&osl=EN&typeid=-1&formatid=-1&servicetag=&SystemID=DIMP4E521&hidos=WW1&hidlang=en&TabIndex=&scanSupported=False&scanConsent=False]
(It might indeed be worth entering your Service tag there, just to reduce the number of different available downloads for you to check through.
Check in particular to see if your BIOS and the video driver for your ATI X1300 is up to date.
There seem to be a lot of firmware updates for hard drives being listed for the E521, so also check to see if there's one for your hard drive. If so, it's probably best to update that too, just in case.
If you were behind on anything and you update, try reimporting another of the CDs that has been importing poorly. Do you get a better import this time?
