I can't upload my program to my Arduino

Development Tools IDE 1.x
1

Hello!
My operating system is Windows7, 64-bit version and I have got an Arduino Uno.

I was able to upload my first program, which was this:

int ledPin=13;

void setup()
{
pinMode(ledPin,OUTPUT);

}

void loop()
{
digitalWrite(ledPin,HIGH);
delay(1000);
digitalWrite(ledPin, LOW);
delay(1000);
}

Then, when I tried to upload another program, even though it's a blank one or the same as the one that I have already updated, I keep getting this error:

Arduino: 1.8.9 (Windows 7), Board: "Arduino/Genuino Uno"

Sketch uses 942 bytes (2%) of program storage space. Maximum is 32256 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Right now, all that my board is doing is to blink the led 13 and the led that indicates the power is also on.

I checked if the board and the USB port are connected were they should be and they are. I updated the driver for Windows 7 as it says in the troubleshooting section, and I have tried some fiexes as well(like the one that implies starting Arduino from the IDE, not from the .ino file), but none worked in the end...
I hope that someone can help me with this problem!
Thank you for your attention, and I wish you a great day!

Remove any connections to pins 0 and 1. These pins are used for communication with your computer, including uploads. Connecting anything to these pins can interfere with uploads.

Make sure you have selected the port of your Arduino board from the Tools > Port menu.

Sometimes the port will be labeled with the board name in the menu. Other times it will not. If you don’t know which port is your Arduino, you can find it like this:

  • Unplug your Arduino board from the computer.
  • Tools > Port
  • Note the ports, if any, listed in the menu.
  • Close the Tools menu
  • Plug your Arduino board into the computer.
  • Tools > Port - The new port listed in the menu is your Arduino board.

Thank you so much for your help, I think the problem was with the port, now I it works fine for the moment. Sorry for replying this late, but I thought I should thank you for your time replying!
