Hello i have a leap frog junior tag and i asked for help before and they sent me this-1) Launch LeapFrog Connect 2) Press and hold down Ctrl + Shift + R 3) A pop up box will prompt you to connect the device you wish to reset 4) Connect the Tag Junior/ Tag Reader and follow the on screen prompts 5) Eject the unit when the reset is complete 6) Close and then open LeapFrog Connect 7) Connect your unit and turn it on 8) You may be prompted the you unit needs an update. Accept this update 9) Sign into your parent account and link a footprint to the current profile. i did all of that and it still only reads one page. please help my son really wants to use it

SOURCE: My computer can't detect the leapfrog tag junior..

I had the same problem. Sat in front of the computer for an hour trying to figure out what was wrong. In the end I unplugged the usb cord and plugged it into another usb outlet and it worked. Perhaps you could use someone else's computer? It seems that the usb connection is quite unpredictable.

SOURCE: The software will not load

Mmmm, do you have more than one system. Only other option is to try uninstalling then re installing the software, leapfrog may of updated it!

SOURCE: Tag will not update

I have had the same problem!! Running windows 7 64 bit. I am stuck in the same do-loop. I tried different usb port (as advised), downloaded 2 different installers from their web site, and verified the tag reader is "seen" under the USB controllers on my PC.
You also should check the following:
With TAG reader off, plug into USB port - if it does not automatically turn on device is defective.
IF it turns on do the following:
Click on the Windows start button (the small icon lower left of your computer). in the search box that comes up type devmgmt.msc and the device manager will open. Scrool down till you see Universal Serial Bus controllers and verify you see the TAG reader listed and verify there is no ! (exclamation point) next to it. If you see the exclamation point it may mean the driver is missing. If this is so right click and select properties, on the driver tab click update driver, on the next screen select browse my computer for the driver software. If you need to specify where to look try c:\Program Files\LeapFrog\LeapFrog Connect\TagUSBDrivers.

This was not my problem so I am still stuck - hope you solution was this easy. Anyone with any ideas I would appreciate help also. Customer service was unable to resolve.
