I'm sorry to hear that.  That's sad.

What's the power supply voltage?  It should be 5.0 volts, approximately;
if it's more than 6 volts, you've got troubles.

The possibilities are very limited:

1. Vcc is too high;

2. Vcc and ground are reversed;

3. Vcc is AC, not DC;

4. Something else is sourcing current into the PIC, causing latchup;

5. PIC plugged in wrong;

6. PIC wired wrong;

7. Pin numbers on PIC misinterpreted; or

8. PIC was dead to begin with.

That's just about the entire universe of possible causes.  Maybe I could
think of more if I had more coffee in me, but I think that's it.

It must be one of the above.

In any case, PICs simply do not run hot unless there is something
horribly, terribly wrong.  And in most cases, they don't even run
slightly warm.
