Enabling Menu button disables all buttons

Here is the error msg I am getting in Chrome. Same behavior in Firefox:

Uncaught ReferenceError: SWFUpload is not defined
(anonymous function)
b.extend.each
b.fn.b.each
(anonymous function)
j
CKEDITOR.event.CKEDITOR.event.fire
CKEDITOR.editor.CKEDITOR.editor.fire
(anonymous function)

The directory is:

sites/all/libraries/swfupload

Should it be:

sites/all/libraries/SWFUpload

Thanks, I'll try to re-install again, but I did follow those instructions.

Got the module working by disabling:

"Delete unused files
To save space uploaded files that are not used in text will be deleted"

I will double check the dir permissions, but in any case, this appears to have been the source of the problem. All menu buttons, including the one click upload are working now.

Problem persists in Firefox. Along with the error:

TypeError: e.getSelection(...) is null @ .../libraries/ckeditor/ckeditor.js?mwlfwq:361

I am also getting this error:

[09:44:47.795] ReferenceError: SWFUpload is not defined @ ...sites/all/modules/ocupload/static/plugin.js?t=DAED:29

Reinstalled SWFUpload and problem seems to have gone away. Still getting this error when page loads, but one click upload button is working in Firefox now:

ReferenceError: SWFUpload is not defined plugin.js:29

from file: CKEDITOR.plugins.add('OCUpload', {line 29

var swfu = new SWFUpload({

Gave up on this approach. I've generally moved away from allowing site users to add images and oembed videos into WYSIWYG long text fields, preferring to setup separate image fields and link fields. The media module and editor based solutions all have various severe limitations that can be managed when only trusted site admins are adding content, but cause endless problems for a social site like mine, RealLifeEnglish.com. I found a great module called Drag and Drop Upload that works with the image field and works great will all major browsers: www.drupal.org/project/dragndrop_upload
