Hi Mary, The API is basically the communicating mechanism between the LMS and your content. If you receive an Unable to acquire LMS API error when launching Articulate content in your LMS, it may be caused by the version of Java that you have installed. Some LMSes use a Java API object to load content. Since content created in Articulate does not require Java, please do the following:
After about 15 minutes of set time use a damp sponge to wipe tiles clean of excess grout, regularly rinsing sponge out in bucket of clean cool water. I do each area twice before I move on to more grouting and will use more than one sponge through the process of the whole room.
Roughly speaking, 30 days. Honestly, it would be best to wait that long to seal it. However, most people - and for good reason - don't want to wait that long. It's too easy for there to be something spilled on it. If you really want to do a bang-up job, do your first application of sealant after 48 hours. Then, 30 days later, clean the grout with a toothbrush, using a strong mix of bleach & water.
