I realised yesterday that my team file corrupted and i lost all of my teams.
I remade my teams but every time i quit WA and open it again teams don't be there.
Dunno what kind of problem is this.

Where is your copy of Worms: Armageddon installed?

C:\Team17\Worms Armageddon

I didn't have such a problem like this since 3 years now though

Do you have full access rights to C:\Team17\Worms Armageddon\User\Teams\WG.WGT
also the team file may be broken. try deleting and creating a new one

Thank you for for the tip. It seems to work.
Is there any way to fix this corrupted team file?

using TeamED (http://worms2d.info/TeamED) you can set back your teams with the needed parameters (including singleplayer completion)

I tried to open it with TeamED but still says corrupted file.

i mean, edit the new team file to the settings like you had in the broken one. you can't edit the broken one itself anymore

Do you still have the corrupted file? Since the team format is known, I may try to restore it if it's slightly damaged.

I still have this file.
Wanna e-mail you?

Can u zip and post it in an attachment?

Here it is.

I almost expected that, it's completely filled with 0 bytes, thus nothing is restorable:

Can this happen if someone doesnt have complete write access to a directory?
Or is a dumb AV blocking write accesses again?
I don't know exactly. Maybe some other have more experiences here (especially cuz I don't use any AVs anymore).

Question to you would be if you or another pc user installed some kind of software or changed your operating system before the problem occured at first time.

Another interesting thing would be to see if you have the required access rights to the WA directory. Right click the folder in a file browser / explorer window and choose "Properties", then click on the tab "Security" and click or username in the list at the top. It should look somehow like this:

Dunno. This is the first time facing this problem.
Anyway, i just re-created my teams and that's all.
Thank you for helping me though.
