Investigating the problem with the cart that appears ( or should) on the sidebar. Theres a workaround if you use My Cart under My Account currently but were trying to see what happened there all of a sudden.
Redownload and reinstall the loco and es44 common deps files, make sure no open for edits and it should be all good.
As far as the limits, there has been far too much sharing in recent times as we were seeing in alot of cases over 20 plus downloads from many different IPs. If you need more please just let us know and we can look at that and regenerate more if needed. Applies to the newer run of items past few months going forward. As always and we have said this for years the end user is responsible for backing up their own files.
