bigstar, I used Translation Pack v1.6. You can see it on a screenshot:

and Russian.sib (Download Source):

All the strings are translated. Probably, there is a mistake at translation from *.sib in *.elg. I repeatedly repeated it. Everything is for my part made, but you do not wish to understand the reason of an arising mistake.
