frd 0.83u1
czshare.com_profi 1.05 [checked]

after enter a valid login and password, report me this message:
ERROR - Problem with a connection to service. Cannot find requested page page content.

frd shows good size of files. if I log to czshare.com, I see a new links in list, after that I click on link is possible to download via browser...
It looks like bad respond link is returned from czshare.com, maybe bad reaction on special characters or czshare.com changed a syntax for download links
I don't know if this plugin supports more than one file downloading. It will be very usefull add this feature ;)

Some links:
[czshare.com]
[czshare.com]
[czshare.com]
I think that on every page will show same error...

Fixed. Update czshare_profi plugin to version "1.06".
The problem was as you said in "special characters", that were different in the url and target link. Now it should work.
