Graph and trace buttons don't work
At first, they just messed up and show a screen from a tetris program I installed. I deleted all the files that came with the tetris program and now pressing either button goes to a blank screen. I can enter values to be graphed, but the graph won't display anything except a cursor when I hold down an arrow key. I enter an equation on the graph such as x^4-3x^3+6x-1=0 into Y1 and Y2 and I get an "ERR; INVALID DIM" but no graph.

If either error occurs when trying to graph a function (not a STAT PLOT), the error can be corrected by turning off the STAT PLOTS. The following steps will turn the STAT PLOTS off, allowing the graph of the function to be displayed.• Press [2nd] [Y=] to access the STAT PLOTS menu.
• Select 4: PlotsOff.
• Press [ENTER].
• Try graphing a function like y = x^4-3x^3+6x-1
