After having eagerly awaited the 1st patch, which was released last week, many of you have reported back several major issues, e.g. that it's not possible (for some) to start a season, that it's impossible get to the 2nd year of career, and that it's impossible to load LAN-games (and there's more...). Obviously, these are all very serious bugs, and Cyanide seems to have worked intensenly on a patch since the release of the 1st one.
According to Eyolfur, Cyanide employee, the patch will "probably be released Monday" (tomorrow). It also seems that Cyanide will release a tool which makes it possible to continue careers based on patch 22.214.171.124 with 126.96.36.199 fixes.
Thanks to ThunderBlaze for the tip.
