Hi Angie, thanks for your Diagnostic Report!
It appears that there is an error in your Microsoft .NET Framework, and this may have been causing your Little Reader to crash so often. (BrillKids software are developed on top of the .NET Framework, so it's very important that this framework works correctly to ensure that your LR will also run smoothly.)
Please try doing a Repair for your .NET Framework by following the instructions in this article:

I hope this helps!
