Hi LNakell,
As Ellis stated there is version mismatch. Please check how many versions of Indesign installed on your machine , if there are two CC and CC2014, then try to launch CC2014 and try to open the file.
If you do not see CC2014 then you can open Adobe Creative Cloud App and install CC2014.If you update or install CC 2014, it will not replace CC to CC 2014 but you will have 2 versions of the same .
