Getting an Error when trying to install the new modpack of BigDig?

[Launders]

I try to launch BigDig and it says it needs a new update which is understandable, so i launch it and it says the following error:

Error unzipping a file for the following pack: Big Dig

Attempting to extract file bigdig-1.0.zip, but did not exist.

Please consult the modpack author

 

Please help me fix this issue.
