thank you for your responses. Let me explain my problem in some detail.
I have been using rapidgator both from my office and my home computers without any problem until 2 days ago.
I have also been using jdownloader without any problem with rapidgator.
Now in both sites (office and home) when I try to direct download any file, I get the message
"File is temporarily unavailable, please try again later. Maintenance in data Center"
This happened for several different files.
In Jdownloader when I attempt to download a rapidgator file, It says wait 59 seconds and then starts to count down. Meanwhile when I check settings page of Jdownloader
it says " (404) session expired, waiting before opening a new session" Then at the end of 59 seconds, in the setting page my status of rapidgator turns to normal but the file in the download page gets into waiting status like for 29 minutes etc. But in the end it never downloads the file.
So in direct download or in jdownloader and in different computers I get the same message and can not download.
I hope you can help me solve this problem.
ps: yes, I am sure I am logged in my rapidgator account in my browser. I tried different browsers , chrome, mozilla, ms edge.
