I have a suggestion to make. In JDownloader 1 downloads that were interrupted were restarted from where it stopped. In JDownloader 2 downloads to be interrupted are reset as if nothing else had been downloaded before. This was especially useful for hosters that the user did not have a premium account. Then I suggest JDownloader 1 functionality is present in version 2.
P.S .: excuse my bad English.

Please provide more information? Host/Free/Premium/Number of Connections?
I ask those because nothing changed for that feature. JD2 resumes at same position where possible like JD1 did.

Basically this occurs with all hosters who tried (uploaded, uploadable, keep2share, datafile, depositfiles, mega, etc ..) in premium or free accounts and even with only one connection on each trial. And since I upgraded JDownloader happens.

Resume works fine, it must be something system specific. Which antivirus/firewall software? I ask this because if not configured correctly they can interrupt chunking, which covers resuming downloads. JD1 configured correctly for exemption and JD2 not?

Please provide a logfile. Menu -> Help -> Create log and give logID
or easier/faster, let's do a teamviewer session.

Sorry, I forgot to say that use Linux Mint 64-bit 17.1 MATE. I do not use antivirus or firewall and not.

And what about jiaz questions? - Any feedback?

Here is a log of the last two days: 29.06.15 15.03.24to28.06.15 16.12.25 jdlog://5293042225341/
I arranged this log from their Jiaz guidelines.

Can you please create new logfile with only one download (where resume fails)
the log only contains datafile downloads failing because of plugin issues. no download issue visible.

There is only problems with DataFile because just tried to download the hoster DataFile. Unfortunately I can only generate logs files of the last two days and I can not make new downloads today because my connection is very unstable. Once the problem is resolved I will return a log file. Excuse me and thank you for your attention.

PS: sorry my english I'm using Google Translate.

[Jiaz]

Datafile had a plugin issue and should work now. Please test again (update first) and in case it still fails, create new log and give logID

[Jiaz]

PS: your english is fine

Problem solved. It was only buy premium accounts download servers. I believe it is a limitation of some servers that limit the free accounts. Thank you for listening, especially Jiaz. Dude you've saved me a few times problems.
