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.
All you need to do is leave the grout to dry before getting it wet. The instructions should tell you for how long. As you and others have pointed out drying and curing are separate things. While you can use the shower after the grout is dried you may need to leave it for a day or two after it's cured before sealing.
