Do you experience problems during downloading?
Check your connection in Status and Interface settings window.
Use Test Server in Config > Servers.
We will probably ask you to do a test using only basic settings.
Do you experience problems during repair or unpacking?
Enable +Debug logging in the Status and Interface settings window and share the relevant parts of the log here using [ code ] sections.
Could it be that you are using Python 2.7?
Anyway, depreciation warning are not an issue.
Just a warning to use that we must sometime upgrade the code.
We do that as late as possible as not to break compatibility with older Pythons.
