Tekkit server on host. INFO Error: Invalid or corrupt jarfile

[Pixeldk]

iam trying to get my tekkit server to run on a host via the multicraft control panel. i make the server use the tekkit.jar and try to start it up. this is what i get.

29.03 17:49:12 [Multicraft] Looks like a crash, check the server console

29.03 17:49:12 [Multicraft] Minecraft shut down

29.03 17:49:12 [server] INFO Error: Invalid or corrupt jarfile /home/minecraft/multicraft/servers/server1581/jar/Tekkit.jar

29.03 17:49:12 [Multicraft] Minecraft stopped

29.03 17:49:12 [Multicraft] Retrying server startup

can anyone tell me what i am doing wrong?

I can't imagine anyone here being able to provide proper support when you are using a server hosts control panel to set up tekkit. There are so many variables we cannot see.
