Userpoints for e-Commerce not working

This is a duplicate of an issue posted with the e-Commerce project - not sure where the problem lies

I want to enable members to pay for tangible items with Userpoints

Initially I installed e-Commerce v 5.x-3.4 and Userpoints 5.x-3.7 and Userpoints-contrib 5x-3.0

Although I set it up so members could redeem their points, on checkout they were able to complete when they did not have enough points, and no points were deducted from their account.

I tried out e-Commerce 5.x-4.0-alpha11 but had some errors (which may have just beeen not installing it correctly) and abandoned it for 5.x-4.x-dev - I also tried 5.x-3.x-dev but same problems, errors, maybe it wasn't installed correctly - I think I shall try it again because it contains the required payment module

I also installed Userpoints-contrib 5.x-3.x-dev and Userpoints 5.x-3.x-dev

Wow, it is really tricky to change versions of ecommerce, I had to delete tables manually, etc. (This thread was very helpful http://drupal.org/node/119432 )

Also, Userpoints_ecommerce requires the payment module which is not included in 5.x-4.x-dev so I copied it from the 5.x-3.4 package and I had to comment out all the credit card functions to get rid of errors (and I don't care about credit cards in this site)

One issue I have is that the only user who can make payment settings us user/1 - there are no permissions for payment, not even in enabled_modules - and the payment module is not included in ecommerce 5.x-4.0-alpha11 either

I don't know if this is an issue with the e-Commerce or the Userpoints-contrib module - or both

I am just looking for a recipe so that the userpoints are usable for ecommerce, points are deducted on purchase, and purchase is denied if there are not enough userpoints

Now on checkout I cannot complete - I get a message from Firefox that the server is redirecting in a way that cannot be completed -

I have not tried Ubercart, I thought using e-Commerce would be simpler, there are only 2 products.

Is payment by Userpoints no longer supported by e-Commerce, or is is an issue with Userpoints-contrib?

Site (in dev) is at flydigits dot netsperience dot org

I am back now to e-Commerce 5.x-4.x-dev and Userpoints_contrib 5.x-3.x-dev
