You just installed Adobe Acrobat 9 Professional and are very frustrated. You have two documents, one in Russian, and another one in English. You would like to create a .pdf with 2 columns, left side for a Russian version, and right side for an english translation.
You've never used Acrobat Professional before to create documents, and some help documentation doesn't seem to want to talk about creating multiple columns at all. You can try adding a column by clicking on "Table" then "Insert" then "Column". You may still need to create a .pdf portfolio then try inserting a column.
