LeapPad Manager Problems

[mrss10]

I purchased a used LeapPad3, reset the information and account preferences to my account and to my sons name. Downloaded Connect and the Manager from here. I successfully uploaded a couple videos, but since then I haven't been able to get the LeaPad3 to connect to the manager. It is fully charged, I'm running the program as an administrator, uac is off, its on its own cord, it is recognized by my laptop. When I go through the manager and click connect, it comes up with a red error box saying the following:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

WRN: Assembly binding logging is turned OFF.

I am not a programmer nor do I have a huge amount of knowledge as to what this all means, but I can follow directions well. Any help would be greatly appreciated!
