Cubase artist set up

Hi i have just recently bought Cubase artists off a friend and im having problem loading it up. i get this error message

String reading from file D:\CUBA#E&\AdditionalContent/Documentation\Engish\Plug-in_Reference.pdf.
Verify that the file exist and that you can access it.
Retry or cancel

I know that the plug in reference.pdf is there for its in the folder that it suppose to be in. but it wont see it and when you hit retry it just keeps coming up with this message. and when you hit cancel it cancels the set up

I hope someone can help cause. im running a Sony Vaio laoptop with i3 processor and 4 gb of ram with 500gb disk
