I ended up cancelling cubedhost and going with hostlegend. After i cancelled they finally responded to my ticket i put in with these instructions
Manual installation is fairly simple:
1) Stop your server in Multicraft
2) Download and install a desktop FTP client if you don't already have one (eg.
http://filezilla-project.org)
3) Download the latest FTB (Mindcrack) zip and extract it to a folder on your computer
4) Open your FTP client and connect to our FTP server using the details found under the FTP File Access tab in Multicraft. Please make sure you enter the information exactly as it's shown; your password is the same as your Multicraft password.
5) Open the jar directory in your server's files and delete everything.
6) Drag the single jar file from your extracted FTB files into the jar folder
7) Find the mods, coremods, and other folders in both your server and extract files. (If they don't exist already, skip the next step)
8) For each folder, delete all of the files inside
9) Drag the files from your computer to the respective folders
10) Start your server
That is what they said to do. Hope that helps. I do know you will need to use an FTP client to upload the files such as filezilla, which is free.
