I receive the following error from my IPN server:

<Quantity>1</Quantity>
<TotalPrice>49.95</TotalPrice>
<Upgrade>False</Upgrade>
<Error>Unhandled Exception: OverflowException Message: Value was either too large or too small for a UInt16. Stack Trace: at System.UInt16.Parse(String s, NumberStyles style, NumberFormatInfo info) at _Default.GenerateLicenseKeys(PurchaseItem item, Int32 count) at _Default.ProcessPurchaseItem(PurchaseItem item, Int32 quantity) at _Default.ProcessSinglePurchaseItem() at _Default.ProcessPayment() at _Default.Page_Load(Object sender, EventArgs e)</Error>
</PurchaseItem>

I set the Last Serial No. file to 80001000, could this be the problem? I have also verified that both licenses are correct and installed in the Bin folder on the server.

Thanks,
Chris

Just a quick update...

Should have noticed the Int16 in the error message. Appears as though serial numbers are limited to 1 - 65,535. License Tracker even rolls over to 1 after reaching 65,535.

While I would have to be exceedingly successful to reach the upper limit , some like to bury product info in the S/N rather than the license key. Any possibility of increasing the upper limit?

Thanks,
Chris

The serial number here is the Infralution Licensing Serial number - which is used to ensure a unique identity for each license issued by the system. It is a UInt16 to keep the size of the keys issued reasonable small. The ILS and IPN code that generates the license handles the possibility of the serial number reaching the maximum and rolls over the serial number. If this happens then your license keys for that product may no longer be completely unique - however you can overcome this if you want to by including ProductInfo in the key.
