Cant open a file in corel 23 it crashes

What!?!?   I can not believe is that I was using corel draw x5 and it kept telling me I was using an illegal program when I wrote to corel and talked to an agent they told me I HAD TO BUY A NEWER VERSION!!! WTF!!! So now I have corel 23 and it freezes everytime I try and open a file. new or old it freezes I have to shut the program down.  Happened many many aggravating TIMES!!!!  Corel does not care AT ALL BUT THEIR WALLETS THEY CARE ABOUT THAT!!

Now what are they going to tell me that I need to buy corel 24?????

I have been sending the reports but no one is answering me or sending me a message that they are working on my problem.  

I need to open up files I just completed and I can not do anything unless I redo all my work each time.  This is not FUN for me when I am trying to get jobs done and approved.  I should be getting my money back for the aggravation and headaches this problem is causing.  I need help in fixing this.....PLEASE!!
