A rather desperate attempt to get a stable system working

As the title says it I have had weeks now of trying to get a stable working environment with Dreamweaver CS4 and Super Suite. Numerous crashes, conflicts etc etc. So I went to the extreme of uninstalling the whole Adobe Creative Suite Web Standard and then re-installing just WebAssist extensions to see if this makes any difference.

I have started by installing CSS Form Builder 2.0.1 (HTML Editor Compatibility Release) first. The blurb about it says:

Features also found in CSS Form Builder 2
- Universal Email
- Digital File Pro
- HTML Editor
- Validation Toolkit

To minimise conflicts it seems logical to me to only install what is needed. From what I see here it seems that by installing this 1 extension I don't need to install Universal Email, HTML Editor or Validation Toolkit. Can someone please confirm with a definitive answer that this is the case. If these extensions are part of FB 2 then is there any need at all to install the others mentioned above, ie. to enable using HTML Editor for a form that was not created using WA Form Builder ??

Thanks in advance.
