Troubleshoot Dreamweaver open and close errors

These two days open Dreamweaver CS4, always popping up with an error that says:

The following JavaScript error occurred while the onload was running recordsetfind.htm:
In the file "Recordsetfind":
Findrs is not defined

A similar error pops up when you close Dreamweaver CS4.

The following JavaScript error occurred while the onload was running teamadmintempdelete.html:
In the file "Teamadmintempdelete":
Deltempfile is not defined

How to solve it? Looked up on the internet and found a solution.

The method is as follows:

This method is suitable for different versions of Dreamweaver 8, Dreamweaver CS3 (9.0) and Dreamweaver CS4 (10.0).

Directory found: c:documents and Settingsadministratorapplication Data

If your version is Dreamweaver 8 and its previous version, please enter the Macromedia directory,
If your version is Macromedia 9 and later, go to the Adobe directory,
In fact, because later Adobe acquired Macromedia, so the catalog is different.

Deletes the corresponding Dreamweaver version folder in this directory. My version is Dreamweaver CS4, then I'll remove
C:documents and Settingsadministratorapplication dataadobedreamweaver CS4 folder,
The same is true of other editions, and here is no longer verbose.

After you delete this directory, the information you have previously configured for Dreamweaver is lost, and the Dreamweaver is reopened, automatically regenerating the deleted folder and saving the default configuration file.
