I shall attest that old patches or versions will no longer work with Cofreedom.
First, i upgraded to the latest patch, 5287. Its so weird that my cofreedom (original file) will not start anymore. I tried the Reshack(ed) file, also wouldn't start.
Second, i uninstalled my CO and ran a registry checker to look for remnants in the registry whatever. Deleted all remnants. Re-booted.
Installed client 5250, then patch 5251-5276. Changed version.dat to 5287.
Then, i ran Cofreedom 1.3 and it was good. Opened CO via cofreedom, good also. When i put my login infos, my CO client disappears. I tried thrice, same happened.
Lastly, after the 3rd try, cofreedom crashed.
This may help others who are about to experiment and run Cofreedom like it was before, to save their precious time.
Warlax said in other thread that, TQ had changed some of the packets.
So, let's just wait for Warlax and Clinton for their updates.
