Thank you for using our services.
We used to send a package with a non compiled resources before 3.5 SP1 to those people who wanted to translate them. Afterwords, we were compiling them for the official release. We have not plan to release a new version till 4.0, except probably some services packs and we will not be able to compile any resources for the previous versions. Starting with 4.0, we will change the architecture and we will make changes in the API which will allow you to translate the resources easier than in the current version.
