Cannot Upgrade to the new version in Joomla 1.5.

Hi everyone..

in all of my customers Joomla 1.5.26 Stable when i try to upgrade the new version, i get this:

SERVER_CONNECT_FAILED, failed to open stream: no suitable wrapper could be found

but in my Joomla 2.5 versions, it goes in without any problem downloads and install all OK.

checked my server links in joomla 1.5, seem's to be all ok.! good path to server, this problem does not let me in to configure the module.!

Any more ideas ??

Thank you

You can download MJ package manually at www.mobilejoomla.com/download.html and install it to upgrade your current MJ version.
