format error in kncounts.gz

[Alexy Khrabrov]

I've created a KN model with SRILM 1.5.5, and then wanted to query it  
remotely.  Got 1.5.7-beta for it.  When loading into ngram -server- 
port, got this error:

[alexyk at corptech]/data/press% ngram -lm model.kncounts.gz: line  
1064849030: reached EOF before \end\ format error in lm file

Do I need any other options for ngram, or it it a discrepancy between  
ngram-count from 1.5.5 and ngram from 1.5.7-beta?

Cheers,
Alexy
