Need help utilizing Beeblex validating in-app purchases with xCode - xcode

Question

Has anyone had success using Beeblex to validate in-app purchases? I have an app that is already live in the app-store with in-app purchases enabled and working. In light of the recent hacking news concerning in-app purchases I am attempting to update it to use Beeblex to validate purchases. The problem is that Beeblex always returns a result saying that Apple claims the purchase to be invalid. I am hoping someone on here is successfully using Beeblex and can post a working example. I am following their advice to let the purchase go completely through, then validate it. I basically just cut and pasted their code right off their website, so not sure what I could do differently.
- (void) validatePurchaseOrRestore
{
//The transaction has been reported as complete for a new purchase of the upgrade. I now make use of Beeblex
//to verify the receipt to ensure the purchase is legit.
if (![BBXIAPTransaction canValidateTransactions])
{
transactionResult = 4;
return; // There is no connectivity to reach the server.
// You should try the validation at a later date.
}
BBXIAPTransaction *bbxTransaction = [[BBXIAPTransaction alloc] initWithTransaction:transactionCopy];
bbxTransaction.useSandbox;
[bbxTransaction validateWithCompletionBlock:^(NSError *error)
{
if (bbxTransaction.transactionVerified)
{
if (bbxTransaction.transactionIsDuplicate)
{
// The transaction is valid, but duplicate - it has already been
// sent to Beeblex in the past.
transactionResult = 1;
}
else
{
// The transaction has been successfully validated
// and is unique.
NSLog(#"Transaction data: %#", bbxTransaction.validatedTransactionData);
transactionResult = 0;
}
}
else
{
// Check whether this is a validation error, or if something
// went wrong with Beeblex.
if (bbxTransaction.hasServerError)
{
// The error was not caused by a problem with the data, but is
// most likely due to some transient networking issues.
transactionResult = 4;
}
else
{
// The transaction supplied to the validation service was not valid according to Apple.
transactionResult = 3;
purchaseDidFail = TRUE;
}
}
}];
}
