vector or matrix error after upgrading from DIAdem 8.1 to 2015.

I have a C++ Program that loads data into DIAdem. Back in 8.1 everything was just peachy but now that I've upgraded to 2015 I'm getting errors to the tune of these:

ChnName(1): Invalid vector or matrix error
CHNCOMMENT(1): Invalid vector or matrix error
CHNDIM(1): Invalid vector or matrix error
CHNATTRTXT1(1): Invalid vector or matrix error
CHNATTRVAL5(1): Invalid vector or matrix error
CHNATTRINT5(1): Invalid vector or matrix error
CHNLENGTH(1): Invalid vector or matrix error

I'm seeing that the channel group is still being created but there are no channels in the group when these errors pop up. My guess is that channels were pre-allocated in the group back in DIAdem 8.1 or something to that effect and that now I'm going to have to create the channel before I can set these properties?
