Error "ProjectOptCurrencySymbolInvalid" emoneda changing PEN type in Project Server 2010

When I changethe currency typeinPS2010Serverto PENdoes not show any error message or warning.

However, after doing so I try to create a new project I get the error message: "ProjectOptCurrencySymbolInvalid" as shown in the imegen.

When you return to euros or dollars, no error occurs. As could fix it.

I hope you can help because it's driving me crazy.

thanks
