:cry:

I hope you help me as soon as possible because I do not want to run out of play. ;D

Do not forget.
It is false-positive

Can you send that file to virus (at) avast (dot) com
and report it as being a false positive?
Maybe adding a link to this thread.
Welcome to forums.

Oh, they usually correct false positives very soon.

Thank you.
More long for them to correct it.
I guess I’m not the only one with this problem in DLL.
More take to get it soon because if not many people will not play this weekend. :-\

Sorry for the double-post. :-[
I clicked on the VPS and start to send this file avast pro.

a3dapi.dll

Now they will analyze the file?
Then send me an update?
Now.
Thank you.

Hi, false positive alert is already internally fixed. Please wait few hours to new VPS update
