CorelDraw X7 HotFix 1 Update4

I have CorelDraw X7 (on windows 7) with a subscription, so I like to keep current with all the updates. I did not encounter any issues after I installed update4. However, I just installed the HotFix1 Update4 and now I can not open ANY of my corel files. This is extremely frustrating! I can create a new document. But any time I try to open a file I created before the hot fix install it just spins and does not load. I do not have any error messages. Task Manager just says CorelDraw is not responding. HELP! I need to be able to edit files I created before the hot fix install! I have restarted my machine and done a Repair to corel draw. It didn't help. What do I do?
