Hey guys, I recently had to replace the hard drive in my computer and I've gone back to set up APM and MP. I followed the wiki as I did the first time I downloaded MP and everything worked fine. Now, after following the wiki, I keep getting "COM Port 4 does not exist" when I try to connect the APM board. I went to Device manager and it seems that it is assigned to Com "Port 2, Hub 4" however, when I pull the drop down box in MP it gives me "Com Port 4 Ardu Mega" as the option. Any ideas on how to fix this. I have the latest drivers installed and the most updated MP.
