Cannot open Virtual Machine

hello,
i recently reinstalled my Mac OS, and my account was changed from admin to standard, so i had to create another administrator acount, and delete the old one. Now, after moving the documents from the old home folder my machine wont start. I changed the permission but with no use. How can i make it work again? I had important work there.

 

It sais that the hard drives are corupted when i try to open them.

 

I am still in my trial period, so, can i use some tool to convert it back to VMware? maybe it will work there...

 

Ok, thanks a lot for your help and effort, As for solving the problem, i solved it myself:

I'll just stick to Sun Virtual Box, it's faster and it's free, AND IT WORKS!
