Connection Key Issues

I have a similar problem.

I am working with a user who has a Mac; I have a PC. We are both using Contribute 2.

I sent him a connection key together with the password.

When he clicked on the key and entered the password, he got the following error message:

--------------------------------------------------------
Your login or password is incorrect. Please check your connection information or contact your administrator.
--------------------------------------------------------

I went round to enter in the password myself to make sure it was entered correctly and I got the same error message.

However when I click on the connection key on my machine and enter the same password, I have no problems re-setting the connection.

Does anyone have any ideas about what's going wrong?

Thanks in advance.

Same problem here. I have a user who cannot connect and is receiving the same errors already stated. The user has tried installing Contribute on a second computer to see if that resolves the problem, but it didn't.

Also, another user for the same site can connect successfully.

We're using Contribute 4.
