Connection Lost then cant find server?

[Truckinve]

Well first hello to everyone!, I downloaded this excellent mod but Im having some problems whit the "connection lost to the server". It also tends to crash after some time to Vista-32bit

I read the Sticky and did the ESC key method and also disabled Windows Defender and ESET NOD32 firewall whitout result, and the option to set the afinnity to the CPU is disable I couldnt check this . Game and mod were also reinstalled.

The problem is strange cause happens when a server has many players whit it,when it fails to connect then it just disappear from the game server browser.

Here are the Specs.
