OK, the language used in that information message is a little abrupt. If you're not used to reading English then it may look like a bad thing.
OK, the first thing to fix is uploading new programs. Any time I have a problem like this, I open the Blink sketch from the examples and try to upload it onto the board. Most boards have an LED on pin 13, those that don't usually have at least one LED that you can blink to see if it's working.
Some of the more advanced boards (Due, Teensy) can get stuck where they won't upload new code until you press the erase or reset button on the board. If you have a reset or erase button, try pressing that, just before pressing Upload on the blink sketch.
OK, so back to the information message. It says you have 194 bytes available for local variables. Do you know how many bytes your local variables take? If you aren't sure what a local variable is, then you probably don't have more than 194 of them.
