First of all, download the latest version of Java( www.java.com) and osbot (www.osbot.org)
Random errors:
If you are using a VPN try switching to another IP address
If you have an antivirus giving you problems, make an exception for osbot, or just disable it.
If you are getting this error:
[iNFO ][08/29/13 09:45:27 PM]: Grabbing parameters... [iNFO ][08/29/13 09:45:28 PM]: Successfully grabbed client parameters from world 69 [iNFO ][08/29/13 09:45:28 PM]: Injecting client...
First, delete your local.dat. Can be found here:
If this doesn't help, let the bot sit around for 5-10 minutes. Sometimes the servers can be slow and take some time to download and inject the client(will take a while if its your first time). If that doesn't work, then close the first tab you opened and then open a new one.
If none of these guides help you, contact any Mod, @Sherlock, or myself. We can help you out.
