I see, so your cDNA amplifies and the internal controls don't.
Just one idea, check that you have a correct setting for a detector (fluorescent channel), in some cyclers (ABI) if the program is run with the wrong detector, the data is accessible once you select the right one. This might save your run if that's the case.
Otherwise you lost your samples for now. Next step would be rechecking that you followed the manual from the array and didn't forget anything. If you are sure about you did, and that the storrage was appropriate, then you can only contact Qiagen to tell them. They may have some ideas too, or they will decide the product was bad send you a new one.
