When I try and get on a server it says the server requires you to have the following mods:

mod_ic2 v.197

mod_computercraft 1.33

mod_ccturtle 1.33

mod_railcraft 5.3.3

I have tried to reinstall it and that did not do anything

Sigh, the server you are trying to connect to has not updated to the most recent version.

[spro99er]

Have exactly the same issue, and ive made sure it is the most recent update off the technic website

[Jelato Foot]

The latest version is the dev build, 99.98% of servers run the recommended build so you shouldn't be running the dev build unless the server you are playing on specifically tells you to.

When I run on the development build it asks me whether I want to update and whatever I choose it still does not work.

What should I do (I am running the server)

Start your launcher, go to options, unselect 'always use recommended builds' and then select the lastest version, that should fix it.
