Getting banned the first time launching the MTA on a new device

[Hikari]

I Bought a new laptop (Gigabye G5 GE) on 24 December. Bought a new laptop (Gigabye G5 GE) on 24 December. Installed the MTA and a clean GTA San Andreas. On first start-up immediately got the error: "Disabling the MTA. Reason: PAID HACK // BYE blocked you". This is my second PC, the first one never had this problem. Neither on my new laptop or on my first pc I've never had any third party paid hack software installed.

Here is my serial from my new laptop where the ban was received:

Thanks in advance!
