There's nothing wrong with you: Puppy can be a bit temperamental. If you have any more problems, it might be a good idea to change (unless you like solving problems, of course).
From the fact that you chose Puppy to start with, I assume you have a small computer. If that's the case (or if it isn't), try
AntiX for 128MB
WattOS for 256MB
SalineOS for 512MB
Mint for 1GB
All are simple and well-behaved.
