The 2+2 converter should work fine - it uses Holdem Manager.
1 - Open your hand history file in Notepad or some other basic text editor.
2 - Select all of the text for the hand you want starting with the line that reads "<game id=" until the line that reads "</game>".
3 - Right-click or otherwise copy the data to your clipboard.
4 - Start up a thread on 2p2.
5 - In the upper right-hand corner of the editor, click on the Hand History Converter.
6 - Paste your text, selecting appropriate options.
7 - Edit the hand and whatever else you want in the post and you are all set.
Below is an example hand that I converted this way.
Merge, $0.10/$0.25 No Limit Hold'em Cash, 7 Players
