Yes, I checked your order (don't post order numbers in public, I've edited it out...), and the only order we have from your email it's ONE order for GSX. Maybe you bought the base GSX from another retailer ?
In any case, what you download doesn't have any relationship to what you purchase. The GSX installer contains Level 2 in the installer, but they are two separate products when ordering is concerned.
If you buy on the web page, what you buy depends on what you put in the shopping cart so, apparently, you put GSX in it.
If you can contact me by email, at the support address listed in your purchase receipt, with a receipt of your original GSX purchase (regardless where you bought it), we can refund your double order so you can order the Level 2 expansion.
