We need a LOT more information...
It sounds like you are using the OOPic S with a parallel programming
cable, true?
How exactly did you connect the LED: to which IOLine, to which pin and
what size resistor? The big startup problem with the OOPic S is that
pin number and IOLine aren't related. The IOLine numbers are
silk-screened on the board but aligning that with the pins is an issue.
Have you checked the +5V? It's probably ok but that little voltage
regulator on the S board won't take much abuse.
Did you unplug the programming cable? Sometimes, the cable holds the
chip in reset. That's one of the bad features with the parallel cable
approach. That, and you have to plug into the other I2C connector to
use the debugging features. You really want to buy a serial dongle
and get out of the parallel business. This one is slick:

You should post your code, just in case.
