Invalid Token in Joomdle config

Hello. I downgraded my Joomla version to 2.5 to be sure that it can work with Joomdle 0.95. But I still have problems with my Joomdle Web Services. Now the error is:

An unexpected error happened: 89159464: Invalid token - token not found | ERRORCODE: invalidtoken

Now as far as I know the token in the Moodle settings should be used just for Moodle 2.0.
Anyone can help me?
Thanks in advance.

I add another piece of information:
if I put the token number found in Moodle Admin the error changes to
An unexpected error happened: 630: Unable to read request
which was the error I had with Joomla 3.2.
Now I'm getting crazy ...

To complete my informations, I put the xmlrpc data on my system. Is it possible that it's not the one that the system requires?

The error is from Moodle, so downgrading Joomla will have no effect.

You're right Antonio, but I'm trying every possible move. If I ask to my hosting provider, they say to me that every door is open and that nothing prevent my XMLRPC to work properly. Then if I click on the USERS, COURSE REQUEST, and FORUMS links of my Joomdle CPanel, I see this message coming out:

XML-RPC Error (630): Unable to read request

like I made some mistake configurating it. I'm starting to be out of options now ...

Another piece of information is this:
If I change the Connection Method, turning it to cUrl, I lose the connectivity between Joomla and Moodle, I get an empty response from Moodle, but the links USERS, COURSE REQUEST and FORUMS now work fine.

That is weird: when you say they work, do you mean you see teh course list at "course requests"? Or just that id does not show an error.

I am sorry, but I cannot really give you any more info from here. As I said, it seems the xmlrpc request is not arriving, but I cannot tell you why.

Thank you again Antonio, eventually I succeded. With Joomla 3.2, Moodle 2.6 and JOOMDLE 9.4!!!!!!!
I can't say precisely the list of operations performed, I disinstalled and reinstalled components many time, but it worked. Now I just have to learn how to use it )))
