Hey Ramon,
We apologise for not responding to this post promptly. Our support for XSI 5.0 is still in the works. Part of the qube 4.0 release was to break apart our application support from the core product. This was so that we could start assigning version numbers to the "job types". The next version xsijt-4.1 will contain the 5.0 support. However we're still working on it to make sure it's ready for public consumption. Is there a particular time line you needed it in?
A.
