Error compiling Mega Wizard block!

Hello,

I am new to Quartus... I am using Quartus II version 8.1 Build 163 10 /28/2008 SJ Web edition!

I created a new LPM SHIFTREG block and when I went to compile it it, I got the following error???

Error: Tcl error: can't unset "::quartus(qip_path)": no such element in array

while executing

"unset ::quartus(qip_path)"

Info: set_global_assignment -name IP_TOOL_VERSION bname

Does anyone know what I am doing wrong....

Thank you all for your help!
