Welcome to Justanswer.com, my name is Dustin.I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.
Was the Artista program working for you normally on this same computer in the past? If so, how long ago?
Or is this the first time you have tried to install and use the program on this computer?
Also, what version of windows do you have on your Lenovo, windows 7, windows 8 or windows 10?
