unable to create Renko offline chart in Matatrader 4

 

I am unable to create offline Renko chart in Matatrader 4. I was able to do this a few days ago, but now when I try to create a EURUSD,M2 or EURUSD,M13 it does not appear in FILE - OPEN OFFLINE. Nothing has change as far as permissions. I am totally stumped on this one. Thank you in advance!
