You're missing a common5.pac, sounds like. Download the CUPASH provided with the Meowmix tutorial. It should have a common5 and all the templates (or maybe just the common5, in which case all you have to do is run step1 to get the templates).
No, MeowMix CUPASH bad.
My CUPASH good.
In other words, don't use the CUPASH the MeowMix video provides, use mine. The reason why is because MeowMix's destroys your CSPs in the creating process.
