Odd crashing Horizons 1.0.10

[juno]

I've updated Java, re-downloaded the launcher, re-installed the mod pack, rebooted the computer, rebooted the server, checked my Java variables and cried a bottle full of tears, yet I'm still crashing. I can log in for a few seconds and then I just crash out. All my friends are able to log in to the server and are stealing all my loots, I just know it.

Help! (Here's the crash log)

Here is the crash as it appears on the server side: http://pastebin.com/gHrmJKrj

The error I see from the server is a bouncy castle error and was fixed by deleting the libraries folder from the ftb install folder. Try doing that on your client first.

Thank you for the reply, but I'm not seeing any libraries or lib folders / files in my Horizons folder client-side. There is a libraries folder server-side.

 

[UniZero]

It is not in the horizons folder but the ftb folder before the horizons one.

 

[juno]

I'm only getting dumber :-D where would that be, I only see the launcher.exe file in my FTB folder.

Even in my AppData\Roaming\ftblauncher there is not a library folder / file.

Ok then where you installed the client on your system. On my system the ftb folder has all the ftb files inside it. Open the options and to to the location it says in the install folder.

Well, it's at least a different set of errors now. I reinstalled just to make sure everything was in the launcher's folder, and easy for me to find. I relaunched and had the same crash, so I closed out and deleted the libraries folder. Relaunch, and it downloads a few more files and then gives me this error:

Try a force update of the pack.

 

[juno]

Force update brought it back to life, but now I'm back to where it crashes a few seconds after login.

If it is the same error as your initial post it maybe related to the artifice mod. I would backup your world and update the server and client to the latest recommended version which is 1.0.13.
