Help Me start .. Somebody please help..

Somebody please help...I have recently purchased the Arduino Uno.. I downloaded the software Arduino 1.0.5...

I was trying out the blink led programming..Here's a list of following problems I am facing:- 1> When i check via control panel it shows "com9" while when I open the arduino software most of the time it shows "COM1" while sometimes it shows "COM9".. Why arduino software does not detect the "COM9" ..Why???..

2 > When I tried uploading the programm first time.. It showed a error message.. Surprisingly the TX led started shining.. I started hitting the reset button but nothing happened.. I was looking at the pc while suddenly I realized that now Rx led had turned on too.. Somehow now both the leds are off.. I don't understand a single thing.. Please someone help me..

Now the software is not programming .. It shows the following message.. (http://postimg.org/image/lpza9r153/)

Please do not cross-post.

Reboot the computer and try again.
