Wininet - Code stopped working, someone check please?

This worked and still works with an item compiled under build 616.

If I copy and paste, then recompile under build 625, web page(s) never return a string.

I don't want to assume this is build 625 because it could be my code even though the 616 version still works.

Could someone take a look and see if my code is missing something I have overlooked, or could test yourself and see if similar problem?

I would be very grateful! Thanks
