I've now downloaded and installed the library that you refer to in the first post, and my code still doesn't display anything. I've also tried the "hello world" example, and that doesn't display anything either.
Just a couple of things to check…
1) Did you delete the original version of the library first? It's important to remove it from your libraries folder as the Arduino IDE may still be using it instead of our version. It is normally installed here:
On Windows:
My Documents\Arduino\libraries\
On Mac:
Documents/Arduino/libraries/
Linux:
Usually found within the users home area under /Arduino/libraries/
Just to be sure I would recommend just deleting all versions of the library you find, restarting the IDE and then reinstalling the version from this forum.
2) I don't think this is the problem but worth checking: Can you try adjusting the blue and white contrast pot on the back of the display. Sometimes they are not set correctly by the factory and this can make it look like the display isn’t working.
I bought the display from you (via Amazon Marketplace) a couple of weeks back, which is why I came here.
Sorry about that, I couldn't match your name or email address to an order. If you still have no luck after you have tried the above can you either contact sales [at] hobbycpmponents.com with details of your order, or via Amazon and we will sort it out from there.
