Adobe Active File Monitor V12 will not start/ program crashes & other errors

Question

I have recently installed Version 12 of Photoshop Elements on Windows XP Pro (service pack 3).
If I try to specify "Watched Folders" PE tells me to start the Adobe Active File Monitor in Admin Tools - Services.
If I try to manually start this service it reports that:
"Could not start the Adobe Active File Monitor V12 service on local computer Error 1067. The process terminated unexpectedly"
If I look at the Event Viewer in XP there are numerous errors reporting that this service has attempted to start automatically with the following error:
Event Type: Error
Event Source: Application Error
Event Category: (100)

In addition the Photoshop Organiser crashes frequently and If I edit a picture and save it to the stack, it does not appear in the catalogue so I have to manually get the picture and stack it with the original. I assume that these problems are related to the above problem.
My original installation co-existed with Version 3 so I uninstalled this old version then uninstaled and reinstalled version 12. This made no difference to the problem.
Any ideas on this problem?

Thanks for that suggestion Michel.
Killing the AutoAnalyzer using these instructions (http://barbarabrundage.com/2013/10/31/the-elements-12-auto-analyzer-adobes-evil-undead/doe s ) does seem to have solved the problem of edited pictures not being saved to the stack - although I have noticed that since disabling the autoanalyzer, when saving a file, the editor almost always now does not display the option window which allows you to choose if you want to save with the stack etc. It usually only shows the JPEG quality selector window.
Its too early for me to say if making this change has reduced the frequency of crashes but it certainly has not solved the problem with the Watched Folders so Im still looking for a solution to this one.
