Hello, I hope the translation is correct enough.

I need help with Karata and clothing for Karata.

On the figure La Femme can be found under Items / Downloads / la femme / Clothing / Karata /

cherry dress this can be applied by double-clicking on the figure

I have purchased and installed the pe bikini program for Karata

The program only appears under Materials. It is not applicable.

The following message appears: This material collection does not contain existing materials.

Do you want these materials to be created? 

Confirm with Yes and nothing happens.

What should I do?

Thank you very much! Helmut
