Z.K.:

You need to delete the stock LiquidCrystal library and replace it by this one. It has the same functionality as the stock library but more performant. If you wish, you can store the stock library somewhere that is not the library folder.Okay, thanks though that sounds a bit strange to me, but I'll give it a try.
Okay, well that did not work. Even though I replaced the LiquidCrystal display with LiquidCrystal_V1.2.1 and renamed that library to LiquidCrystal, it does not work and gives me the same error as before. Now, what I am wondering is whether this library is specific to either a 32-bit platform or not. I am using a 64-bit platform with 64-bit Arduino IDE. Could this be the problem? Perhaps I will install the 32-bit version of the IDE in virtualbox and see what happens.
