Shipping doesn't work without logging in

[vibinr]

I think this question has been posted quite a lot of times (as I saw in search), but none of the solutions mentioned have worked for me.

Thing is, Virtuemart works perfectly if the user is logged in. But not when I use "Checkout as Guest".

If I'm logged in, because "Auto selected shipment/payment" is checked, I see the payment gateway selected on the checkout page.
Like this: http://cl.ly/VN9F/Screen%20Shot%202014-05-06%20at%208.04.36%20pm.PNG

If I'm not logged in, no shipment method is selected, and when I click on "Select Shipment", it says "We are sorry, no shipment method matches the characteristics of your order".
It looks like this: http://f.cl.ly/items/0y2R3h1u163y0D3L443i/Screen%20Shot%202014-05-06%20at%208.03.59%20pm.PNG

Any sort of help will be appreciated.

and when you switch on debugging what does it say?

Shipping cannot be shown unless any required address info (eg Zip, country) of the shopper is known; with registered this is already known, but guests must first enter their billing address for shipping to be calculated.

I switched on debugging, but when I go to Tools > Log > com_virtuemart.log.php, there it says -

"ERROR vmError: vmPdf: For the pdf, you must install the tcpdf library at /Applications/MAMP/htdocs/pavins.in/libraries/tcpdf"

So I downloaded the tcpdf package and installed it. Now there's a "tcpdf" folder in my /libraries folder. But still, the same error shows up.

Shipping cannot be shown unless any required address info (eg Zip, country) of the shopper is known; with registered this is already known, but guests must first enter their billing address for shipping to be calculated.

Actually, the guest user is given all the fields to enter - zip code/country/address etc. After entering all these and clicking "Checkout as guest", I get the error.

BTW, both of you, thanks a lot for taking time to try answering my question

Wouldn't worry about the pdf library for the moment - will have no effect on this problem
The reason I said to use the debug is it should print out (on the screen) all the shipping etc calcs it is doing - in there you should see why no shipping method matches the data sent

have you got shopping groups selected in your shipping methods? You shouldn't  - it should be blank i.e. all groups

Man, you're awesome!

Didn't think it was this simple. I just removed Shopper group from Payment methods and Shipping methods. Now it works.

Noticing a one more small problem on the checkout page.

When I try to checkout as a guest, I see an error message saying "Invalid Credentials. Please try again".
Here's the screenshot (Billing information hidden intentionally) : http://cl.ly/VONd/Screen%20Shot%202014-05-07%20at%2012.28.16%20pm.PNG

In spite of this error, I can go through the payment gateway just fine. (Shipment/Payment automatically selected)

Doesn't look like any error I know from VM - would assume it is from your payment plugin/gateway
