Dear god this is frustrating. Every single time I want to use my arduino after I unplug it I get this error when uploading.

I'll be using it just fine for days, but if it gets unplugged and then replugged in, NOPE. How in the hell do I fix this?! Googling this error just gives me check to make sure your ports are the same, or uninstall and reinstall. I've done all this. With no luck. Arduino is COM3 in device manager, arduino IDE has COM3 selected. No matter what I do I can't upload. I use the same USB port on my computer every time, I never switch it. Although I have tried uninstalling, using a different port, then updating the driver, still no avail.

I've uninstalled and reinstalled many times, shutting the computer down after uninstalling etc. No matter what I do I can't get my arduino back up and running! I thought the draw of this was easy to use? That's why I switched from MSP430. ugh Any ideas anyone?

The only time i have this problem is when i have the serial monitor active, meaning that the port it in use

I don't know what that does, and unless it's active by default I definitely don't use it.

Can you use Arduino sometimes now? because if the error is persistent, probably is the Bootloader, if not I suggest you to try this mod with an updated WinAVR: http://arduino.cc/forum/index.php/topic,118440.0.html if works good, then let me know.

I installed that, and blink uploads just fine, but my code doesn't. It doesn't recognize an external library I've added. Do I need to configure something else?

Well, that's another history. You have to copy the library to "Documents/Libraries" but if it does not compile you need to find something related with the library (like a new version in the author's website).

If I had the libraries in the old IDE do I need to place them somewhere else? If so where? In the newly installed IDE there are no folders in the main Arduino folder.

Actually I found out where to place them, and I did, so there's no compiling error but now the library doesn't work.

Actually, it's not just the library that doesn't work. Nothing uploads to the arduino now. I don't have the avr no sync error when I hit upload, just nothing seems to upload even once it says done uploading. wtf

It is the correct serial port and board selected? Can you load a blink example?
