Ahhh!! Zombie run!
That was posted in September. I have no clue what version works now... I would suggest you just test it yourself. Seeing as it hasn't been updated, I would assume it is still the version below the recommended version,
That isn't your launcher version, your Java version or your AV. Without actual info (like an error log, your OS bit, your LAUNCHER version [not Minecraft version], and actual Java version and your antivirus) we cannot help you at all.
This would be better suited in the Tekkit bug boards. If I may however, before you post a bug report, try to make sure you have all of the necessary info (Java Version is very important along with an Error log)
Tip 1: Don;t post your email on the internet like that (You will end up with a lot of spam)
Tip 2: There is a place for this
Tip 2b: This isn't it
Tip 2c: THIS is
Holy coincidence Batkaker! I was just looking at that. Though the forum doesn't bode well, I tend not to put too much stock in Steam forums (they just aren't moderated as well as these ones )
I find it interesting that all of the reviewers failed to mention Minecraft... They got all three major FPS but no Minecraft.
Can you actually fill out the report please? Newest isn't a version and the newest one isn't a Java version. Also, we really need a log to be of much help.
Then you should try posting a bug report. That gives us all of the important info that we need to help you and ensures that the OP of this thread gets the help he deserves.
