[MP4] Impossible to start Trackmania 2 Canyon title ("cannot load file (1)")

[hydargos]

Hello

(This is my first bug report here, feel free to tell me if i'm doing something wrong.)
Since a few weeks, everytime I start Canyon, it download a 61.2 Mo update. The update installed, i was able to play, but the download restarted when I loaded another title and go back to Canyon.
Also, i wasn't able to start Canyon offline: I had a message saying me that i needed to connect to the Maniaplanet servers at least one (i've already done this of course), or the interfacfe disappeared and i was only able to see some clouds with a green-violet sky. (sorry for the lack of details).

But since the 28 march update (i think), i have the same bugs (impossible to start offline and download the same 61.2 Mo update evetrytime), but when online, after the download is finished, i have this message (translated from French):
"Cannot load file. (1)
(downloaded from https://files-v4.live.maniaplanetDOTcom/titles/1a40f048ba/
TMCanyon@nadeo.Title.Pack.gbx)"
and a "OK" button.

My computer is a HP Envy 15-ae112nf Laptop with WIndows 10 family 64bit, Intel core i7 6500U, 8Go of ram, 1TO hdd with 2 partitions (20 Go left on the main partition, where the os and Maniaplanet are installed) and a Nvidia GeForce 940M Graphic card with latest driver. (more specs here: https://support.hpDOTcom/us-en/document/c04933755/ )

I have tried to reinstall Canyon by deleting the files in Documents/Maniaplanet/Packs/TMCanyon@Nadeo.Title.Pack.gbx and in ProgramData/Maniaplanet/packcache/TMCanyonXXXX, then I tried to start canyon again, it downloaded the files but nothing changed.

I haven't tried to reinstall ManiaPlanet.
I haven't found any logs about it in LogCrash folder. If you want more logs, informations, or this message translated in french, feel free to ask or tell me what to do.

Thanks

EDIT: I can start Canyon when I click "Later" when it ask me for the 61.2 Mo update.

Hi hydargos

You could try turning off Windows Defender and any antivirus programmes you have while downloading/ installing the TM updates... These sometimes cause such problems.

Cheers.

Hi,

Nope, I disabled my antivirus (Avira) and Windows Defender, but nothing changed :/
