JS 2 >> new problem with signature change

[MartinG]

Hi,
I was just trying to work on an old Cubase 4 project from 2008 again.
Now I'm running Windows 7, so the project has never played on this system before.
My problem: there are some signature changes from 4/4 to 2/4. I've checked the "follow signature changes" box in Jamstix, but the 2/4 bars are still played as 4/4, filled with silence in the second half.
I've tried 2.5.3b4 and 2.5.2 - but the project was created with an earlier version. Could this be the problem?

Click on the part length of the first 2/4 part in JS and double-check that the time sig there shown is 2/4. Also, double-check that time sig changes in the host occur precisely on bar downbeat not slightly before or after.
