Old Presenter ( must be ver 7 or 8 ) content display problem in our current Learning management system ( SABA)

we are on SABA for our learning needs. Since years content is been loaded on SABA for our learning needs. For last 2-3 months we are noticing that few ( not all) of our old content stopped displaying on SABA, giving a blank screen on the browser . this problem is on a incremental pace. After examining we found that if we repack the scorms again like from ppt to scorm creation it is working fine. but this process is a time consuming process, does anyone know of any better solution than this as we have few hundreds of content .
