Need help transferring data from STATA to HLM7

[thewatcher101]

I need HLM 7 to do nested model regressions. 

The error that is coming from HLM 7 is that the number of variables exceed 8 digits and HLM 7 can't use them. 

My identifying codes already have been truncated to 8 digits and I remove any variables, irrelevant to my analysis, that might caused any issues.

The same issue keeps showing up. I have run out of options on what to do. 

Does anyone have suggestions to what I can do to my data files so HLM 7 can read take them in.
