Error creating a new component Qsys

Hello all,

i'm trying to a integrate PLL ip component in Qsys.

The error says "Error:

while executing

"__altera__safe_load C:/altera/14.1/quartus/bin64/qcl_pll_tcl.dll generic_pll"

("uplevel" body line 1)

("package ifneeded ::altera::generic_pll 1.0" script)

invoked from within

"package require ::altera::generic_pll" and also

"Error: An instance of Altera PLL could not be created.

The component had an unexpected internal error."

I tried to cancel the cache as shown in the Altera solution if you search in internet but doesn't work. I tried to reinstall the Quartus software but still doesn't work. I need this PLL ip component in my project..anyone can help me? I'm using Quartus 14.1 on my PC.

Thanks!
