Zou,
Thank you for your tellings, and I already knew about LV8.0 evaluation edition one. and know its properties too.
my meanings it that, we are using LV7.1, maybe want to upgrade to LV8.0, I doubt whether the Toolkits which purchased with LV7.1 , it can be use in LV8.0 ?
if sure, we don't need to purchase more.
