MY ZOOMBROWSER EX 5.8 TELLS

Question

MY ZOOMBROWSER EX 5.8 TELLS ME "CANNOT DETECT CAMERA. CHECK CONNECTION TO CAMERA, THEN RETRY". I PROCEED TO UPLOAD LATEST VERSION 6.1.A AND THEN WHEN I TRIED TO UPLOAD THE PICTURES FROM THE CAMERA TO MY COMPUTER IT TELLS ME "NO IMAGES TO DOWNLOAD TO THE MEMORY CARD". SO I DELETED ALL VERSIONS. RE-INSTALLED VERSION 5.8 AND NOW IT TELLS ME THE SAME THING "CANNOT DETECT CAMERA. CHECK CONNECTION TO CAMERA, THEN RETRY". I'VE TRIED EVERYTHING NOTHING WORKS, LAST NIGHT EVERYTHING WAS FINE AND I UPLOADED PICTURES SUCCESSFULLY.
