Not sure where to put this as it's actually not an altbinz issue, rather a Bitdefender one.
Last night I had a long queue running, only to find my pc shutdown in the morning without having finished the files, about 20% were done. I couldn't log into altbinz anymore, Username/password were not accepted, it kept retrying.
Changed password --> no go
Tried many other versions --> no go
Deleted config.abz --> no go
Copied C:\Users\Anwender\AppData\Local\Alt Binz-folder from my other PC where it all worked fine --> no go
Tried the freeware version 0.25 --> would not connect to my newshosting account!
This is where I started THINKING a bit, rare occasion.
I went to my security setting and found out Bitdefender had disabled altbinz from my whitelist, well yeah, re-enabling it did the job.
Hope this helps somebody someday.
altbinz v0.47.3.6
Windows 10
x64 system
BITDEFENDER Total Security v26.0.32.123
cheers
