So I recently loaded teensyduino onto my PC. I have a bunch of arduino sketches that previously worked fine.Since uploading the teensyduino many of my arduino Uno sketches not wont compile.I keep getting mutliple compile errors on files I have uploaded dozens of times before.I uninstalled the Adruino IDe and reinstalled in and I am still getting the same problem.I am not sure if this is the correct place to post or not.I have posted on the arduino forum too.I am guessing some libraries got corrupted by the teensyduino, but I am now dead in the water because I need to upload so UNO sketches into devices that I am selling and I catn get the sketches that worked fine previously to compile.I even tried downloading the sketches from the internet in case my souce files were corrupted and I get the same errors.
