UPSXML Module returning empty results

[Marooned]

I got it to work

I changed $this->use_exec = '1'; to $this->use_exec = '0';

I also changed
$this->host = ((MODULE_SHIPPING_UPSXML_RATES_TEST_MODE == 'Test') ? 'www.ups.com' : 'www.ups.com');
to
$this->host = ((MODULE_SHIPPING_UPSXML_RATES_TEST_MODE == 'Test') ? 'wwwcie.ups.com' : 'onlinetools.ups.com');

works great
