looking for assistance with an issue in the MATERIALS TAB, I accidentally created downloading product

[ChiefWendy]

In my plan-project the Materials Selector is now Super slow after an updated product + Materials download.  Have CA 2014. Work progress is stymied after downloading current product to the library. Screen displayed "successful 84,000 ++ products" too much!? Now Materials selector spins & spins takes several minutes to load.  Meanwhile when the materials selector does finally display (like 7 minutes later!) none of the new materials are showing up in the library, i can live with that if i have to but now I can't change any surfaces in my project w/o waiting forever.  Do i delete the recent downloads? move them? Assistance or suggestions please?

yes, thanks = Home Designer 2014. 

Downloaded the latest products & materials available in the program.  Several of them. Definitely didnt update the library after the download.Not sure even how to do that?

the Materials selector is the tab for altering the finish or texture in the plan.... changing the flooring or paint, wood finish, etc.
