I would like to add that the same thing happened to my code. 
And I have just reinstalled MikTeX.

Dear Herbert, 

Where should I put "stepFactor=0.1" ?

Here? 

    \psplotImp[algebraic,linewidth=1.5pt,
linecolor=blue,stepFactor=0.1](-3.79,-8.10)(5,3.00){x^3*y+2*y^2-(-6)}

And I would like to add two more questions: 

1) is there a control sequence like \LaTeX to write PSTRICKS in a sort 
of a logo? 

2) the output of my file (ps) is starting too low in the page, as a result 
the bottom of the page doesn't show up. I use both geometry and crop 
packages and everything is working fine. I can send a sample page and 
my master files if there is someone interested in seeing what is going on. 

Thank you. 

Best regards, 
Luis
