[UPDLIB] [ERROR] Download manager: An error occurred inside the WinINet library.
[UPD] [INFO] Downloading of 'http://perspeak.avir.../idx/master.idx' to 'C:\Documents and Settings\All Users\Application Data\Avira\AntiVir Desktop\TEMP\UPDATE\idx\master.idx'.
That is repeated many, many times, and at the end it says:
[UPD] [ERROR] Generation of update structure failed. UpdateLib delivers error 537.
I have absolutely no clue what's going on or how to correct it. If there is a way I can do this without reinstalling Avira or anything like that, that would be terrific. Maybe my firewall is blocking it or something? I have Windows XP, and a Dell Dimension C521. Thanks so much for your help!
