Well I went to ftp://ftp.kochmedia.com/pub/Anno1701 as suggested by someone here and downloaded the UK 1.4 patch.So far the game seems to run well.
An interesting thing is that when I checked to Anno.exe file by right clicking on it the file version ends up as 188.8.131.523 However, the patch readme has this:
- Fixed a bug within the multiplayer-connections
- New quest reward: Ships
A new (rare) Trader assignment has been included for which the player can receive an Asian War junk as a reward.
- A menu area "Custom content" has been added whereby the player can load and play Maps created using the World editor.
- New populace feedback speech messages have been implemented in order to increase the degree of variance of the different inhabitant statements and sayings.
- Various changes have been made to enable owners of the addon (with the main game) to play with non-addon owners in multiplayer mode.
