Upgrading From Phprunner 5.2 To 6.2

Dear Sirs,
I have several complex projects developed with the 5.2 version. When I try to read one of them with the 6.2 trial version of PHPRunner, I get a pop up error message in the middle of the loading process:
"Application error occurred. Crash dump file is saved to:

C:\Users\<myusername>\AppData\Local\Temp\TrialPHPRunner14670_7.dmp"
This is a binary file, I don't know how to read it. But, beside it, when I click OK in this pop up, PHPRunner closes and I can't do anything else.
Can you help me with this?
Thank you in advance.
