Is Corel Draaw 9 Compatible with Widows 8.1? I have a client who is using corel 9 and I must use it to deliver files so I purchased a new corel 9 suite never used. But the test files between us aren't opening on my end or their end. Any suggestions?

The installation went fine and I've designed and saved a file. The file transfers fine but upon open of client's computer the file opens to a blank graphic file with nothing. But they can see in the file properties that something is there by the file name, size kb etc. Any suggestions? I'm thinking of getting an inexpensive computer with an older version of windows, since I've seen many people state corel 9 works fine on older windows.? I appreciate any suggestions. Thanks!
