avrdude: stk500_getsync(): not in sync: resp=0x00 avrdude: stk500_disable(): pro

hello ~ I am a newbie and need some help. I have a Arduino Uno and was doing well with programming and such. Now I am getting this error message : avrdude: stk500_getsync(): not in sync: resp=0x00 avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51. I have uninstalled the board and port and reinstalled the latest arduino 0023 and still am getting this error message. I am at my wits end. It all worked yesterday and now it's not working at all. If anyone has some insight please post :)

Did you read the first 2 posts in this subforum?

If the answer is ‘no’, we don’t want to hear it!

I did read the posts, more than I care to count. That is why I was seeking help in this forum. Thank you for your kindness.

Capital!

Then pray, what result did you get doing the 'loopback test'?

Do not let me detain you!
