Importing Mail from Outlook via Zoho Migration Wizard

Importing Mail from Outlook via Zoho Migration Wizard

All I want to do is import my mail from Outlook into our zoho mail account but I want to keep the file structure I have in outlook. I've tried converting them to .eml zipping and uploading but everything just get dumped in my inbox and we are talking about 3500 emails. What I want to do is keep the files in the folders they are currently in and import that into zoho.

From what I can tell if I use the Zoho Migration Wizard this is possible. But this nifty little app won't work for me I get the following when I load the application:

Window loads with Zoho Migration Wizard on it and a 'Next' and 'Cancel' button it before I can press anything I get a popup window that says 'Checking Redemption reistration...' then I get another popup that say the Zoho Migration Wizard has stopped working....close program.

I've tried running this as Administrator but the same thing happens. I am running Win7 64bit any help would be massively appreciated!

Many thanks,
Carl.
