Hello, welcome to JustAnswer my name is ***** ***** I'm one of the experts who will be assisting you today.

If the zip file is not corrupted you should be able to uncompress it with WinRAR.

You can download it here:

May I start a remote session so we can work on the problem together from your computer?

I will be the person helping you today. I can see that you may need a little bit of extra help. May I start a secure remote assistance session on your computer and help you resolve the problem? Once the remote session begins, we will be able to communicate via a chat window on your computer.

Thank you,

I rather not do a remote session thanks

Expert:  Jason Jones replied 1 year ago.

I offered the remote session because more often than not, customers prefer that option. If you don't follow the instructions I give you correctly, you may create more problems and/or lose the data. I don't understand why one would choose to not use the remote session, but I am not paid to understand. I am paid to consult, help, and fix problems. It appears that you don't want me to do that. I respectively ask you now, if I may opt out of the question and allow another person to continue with you. May I opt out now?
