Adz, do you really think this is the thread to ask that question? The first paragraph is the only one related to this thread (maybe the second). There's a very high chance it's just you, and a small chance something is broken. 99% chance one of the following will fix it.
Make sure you have the right board selected in the arduino program. (328 or 168)
Make sure you have the right port selected.
Disconnect everything and reprogram.
Try doing a manual reset before programming.
If I've learned anything from working with micros, it's ALWAYS (my) user error and it helps no one to get angry or point the finger.
