Designer Perspective in Eclipse is inactive

Sirs:

I have been using Eclipse Designer 5.8 in Eclipse Helios Service Release 2 Build id: 20110218-0911 for several months.  Now, when I try to edit one of the .activiti files, I get the exception shown below.  After trying various things:  restarting Eclipse, rebooting the PC (Windows 7), I decided to try to reinstall the Activiti Plugin.  The Update Sites provides only version 5.9.  I would like to continue using 5.8 untill I reach a clean breaking point in my project (at present I have been tasked to create some load tests for the workflow engine in version 5.8 to use a a benchmark for load testing 5.9).  I have worked a little with the 5.9 Designer and it has some huge advantages over the 5.8 designer, but for this project I need to work with the 5.8 Designer.  One of the bpmn20 files whose related .activiti file I cannot update is below. 

Is there a way for me to download the 5.8 Designer? 

Do you have any other suggestions for how I can continue to update my 5.8 processes (the .activiti files)?

Thank you for your help.
