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.
Usually directions tell us to grout within 16-24 hours when using sealer as a grout release. I would grout 2-10 hours after applying the sealer to be safe. After grouting, do the final cleanup either the next day or a few day later to allow the grout to cure. You can apply sealer on the tiles and grout after waiting at least 3 days.
