DW CS5.5: Javascript error while executing onLoad in Date_beforeSave.htm Not resolved for me!!!

Question

Hello,
I'm having trouble when moving or renaming files. Linked files are automatically updated, but the following error message appears for each file: "While executing onLoad in Date_beforeSave.htm, a Javascript error occurred".
I tried the solution found in a previous discussion (http://forums.adobe.com/message/757114#757114), that is to say: deleting the .dat file located in the "Applicaion dataAdobe\Dreamweaver CS5.1\Configuration" folder. But it doesn't work.
I also tried by reinstalling the whole CS5.5 pack, but no result.
I also had trouble while installing the CS5.5 Web Premium pack (on Windows XP Pro). Maybe the 2 problems are related?... As the installation was done, an error message appeared saying that some errors occured. Here is part of the error status:
"- 0 fatal error(s), 14 error(s), 11 warning(s)

Please, can anyone help?

Answer 1

OK, I'll try to explain more clearly (excuse me if my English is imperfect, because I'm French).
In fact, I'm facing 2 problems, which could be related or not.
First, when I installed Creative Suite 5.5 some months ago, I received an error  at the end of the installation. You can download a copy of the report here: https://www.box.com/s/5m4k6xv68h00cpumwil9
However, I could use the Adobe softwares without observable problem... until those last days...
So, second and really annoying problem that I only detected those last days (maybe I didn't use the implied function before, but I'm not sure). When using DW, if I want to rename or to move some HTML files in a defined website, all the linked files will be automatically updated. As the automatic update is proceeding, I receive, for each updated file, the following error warning: "While executing onLoad in Date_beforeSave.htm, a Javascript error occurred". And I have to click "OK" to each warning in order the processus to go on. The result of the automatic update is uncertain: some files have been properly updated, some other not.
As I already explained in my first post, I tried (unsuccessfully) to resolve by those two means:
deleting ".dat" file in the "config" folder
reinstalling CS5.5 (same error report received as when I first installed).
I hope that I've been more clear that time and that you'll be able to help me! Thanks!
