Bonding two t-1'S from cisco 7200 to cisco 2600

Ok. This problem has plagued me for the last 3 weeks or so. I have a cisco 7200 routing a channelized DS3. I have two ptp t1's coming back to a cisco 2600 with two WIC cards. Here is my problem. I believe something is wrong with either the multi-link or overload, because they do not balance. When I terminate the T1's seperately, they work perfectly. When I bond them, all the bandwidth is taken by the first person to access it. It then kill the line if anybody jumps onto it. I tried only passing publics, I then tried nating publics to privates, and yet nothing seems to solve my problem. I will show you the configs to see if anybody sees a problem.

this is the TEC config

any help on this would be greatly appreciated, its critical I get this finished ASAP. I have tried many different ways of using hte overload and the multi-link with no luck. I was wondering if im missing anything.
