Title: Cross-compatibility of memoQ 2013 R2
memoQ 2013 R2 is cross-compatible. As a translator, you can connect from a memoQ 2013 R2 client to a memoQ 2013 server and vice versa: from a memoQ 2013 client to a memoQ 2013 R2 server. You can check out an online project, and synchronize the documents. However, you cannot work cross-compatible if you receive a package from an online project.
