Hi Frederique,
A warm welcome to the eForum.
Error 1128 Codes are caused in one way or another by misconfigured system files and in most cases require a deinstallation and reinstallation of the software drivers.
If you simply take a look at out
VMC software downloads where you can find our latest Vodafone Mobile Connect software.
Once you have done this then there should be no evidence of the error 1128.
If you have any further queries, please feel free to let us know.
Many thanks
Andrew
