I'm experiencing the same issue. I have the most recent version of Java (6, Update 32) and I've republished my course in Presenter and I still receive an LMS API error message. We have a license on a couple of computers and I'm receiving the error on the other computer as well. Any thoughts?
Grout needs between 48 and 72 hours to dry before it can be properly sealed. Despite the fact that grout often looks dry within a few hours, sealing it too early can damage the grout and keep it from effectively doing its job. Keep Learning.
How long after grouting a floor do I have to wait before mopping? A: It is best to wait at least 72 hours before mopping a newly grouted floor to make sure the grout has a chance to cure completely. This also allows enough time for the adhesive substances on new tiles to cure.
