Is anyone else having problems trying to sideload .bar app on 10.3.1?

I have a snap2chat bar file which i was trying to sideload on my z10, but the blackberry playbook manager on google chrome won't do it. it shows an error saying that this isn't a zip file!!
The bar file is completely functional as i had installed it on 10.2.1.
If anyone knows how to get past this issue, then i would be grateful for your help.
thanks in advance.

Loaded snapv3 via sachesi no problem.

Pretty vague description of your problem.

You can always download Zeus Browser from BBW. It's the updated version of what you are trying to sideload.
