Problems downloading expansion files

Problems downloading expansion files

I've uploaded my app to google. It has been published. My main exp file
was uploaded with app version code 2 and it still bears the same name. My
main app is right now at version code 4 and is still using the main.2 exp
file.
I've already tested the file with my app through debug.
I've created a test account and i'm signed in on the device with that
account and tried downloading 20 minutes after creating that test account.
I believe my file size is correct too. I'm using the the size from the
properties 155,630,535 bytes and set it to 155630535L. There is another
one called as size on disk which I'm not using.
I've uploaded my apk over 12 hours ago.
Really don't know where I'm going wrong. The only thing I wonder about is
my version name which is 1.13. Do I need to use this anywhere?
I'm having problems downloading my expansion files. Initially I was
getting 'download failed because you may not have purchased this app'. Now
after recompiling (export file) the apk file and uninstalling it and
reinstalling it to my device, I've uploaded it to my publish account and
now I get 'resources could not be found'. Please help...
