Hello,
can you please help me. I have entered my premium login details into the uploaded.to free plugin instead of the premium by mistake. Now whenever I want to download a file with free uloaded (my premium has expired), it always says ERROR - No number between " and 'seconds' was found.
When I tyr to delete the username and password, it won't let me, saying: You have to fill username field.
What can I do?

You can remove login details by deleting the plugin configuration file. It is located in the configuration folder (Help > Browse to log file > one level up). Delete "plugin_UploadedPremium.xml" (or similar) and restart FRD.

That did it for me. Thanks a lot for your help!
