I contacted tech support for the app I purchased & they referred me to mobihand.com. I installed a test app from mobihand & the app company is sending me a code to enter so that I won't have to pay for my app again (btw this is the 1st time I have ever paid for an app & it wasn't cheap). I had installed Astro while waiting for their response, but maybe won't need it now... thanks for your help Mr. Nobody
