Getting "Unable to write cache file" message in DW CS4

Question

I was having some issues with a Javascript message, so looking for possible solutions, I came across “Deleting a Corrupted Cache File” in the Index to Dreamweaver FAQ located on this forum. I decided to give it a shot and carefully followed the instructions on my Windows XP, deleting the suggested cache file in my Configuration folder. That didn’t help make my Javascript message go away, though I did eventually find a work-around for that issue.
However, after deleting this cache file, I began to get the following message every time I close my program or change sites in local files, “Unable to write cache file ‘C:\Documents and Settings\...” the message ends with the site name and the extension .dws.  If I go to Manage Sites and turn off the Enable Cache button for that particular site, I no longer get the message. But if I turn the Enable Cache Button back on, I get the message again. It gives this same message for all the sites.
I’m hoping others have had this issue and there is a simple fix. I can’t say for sure that deleting the cache file in the configuration folder caused this, but it was only after that I began noticing the problem, so it would make sense the two are likely related.
Also, I wonder how important the cache is. I could just turn off the Enable Cache Button for all the sites as a work-around if there's no quick fix and if it’s no big deal.

First of all, only delete cache files when DW is shutdown.
Also, there are a few different caches. That article only addresses 1 of them. Take a look at this TechNote to be able to find the Site .dws cache files:
