This second message you're getting always pops up when I load a Gen 8.1 figure; I just click okay and the figure loads fine.
Likely because you have a lot of morphs in your library and also a lot of [Warning] messages in the log file.
That message should not appear, it is because you have a single morph that uses the exact same label as another in your library. The log file will list the two morph files that have the identical line., The more errors you can eliminate the faster your models will load, up to a point. If you are collecting morphs the load times increase as DAZ has to load every single morph for that generation every single time you load a character. It is just the crappy way DAZ handles character morphs. If you want the load times to get back to normal get rid of the bulk of your morphs and stick to ones you use all time.
If you're trying to load in a character and you have a lot of morphs, than DAZ has to load in ALL the morphs you have for that character, and that can take a while. You might want to take some of the morphs and move them to another folder until you need them, or just uninstall them to speed up loading times.
