having error 67 messages when tethering to cradlepoint

[enettrek]

First off I'm trying to use a tether hack for my tp2 with a cradle point mbr1200. I keep getting the registration 67 error when trying to turn the tp2 in internet sharing mode..I've done the ICS_and_WModem_Fix.cab but it still gives me the error 67.. I'm wanting to use the tp2 as a secondary device with my verizon aircard to give me a little extra bandwidth.

Has anyone got any ideas? I'm running the stock 6.1 rom with no hacks... eventually I'll use the mightyrom but for right now I need to be able to use it as my verizon card has some dead areas for some odd reason.

Thanks in advance
