Group Calendar Install Failed, wp-content write OK. Files look there.

Using WP WPMU Dev Plugin Installer. Clicked to install BP GC. The install said that it failed and to check the wp-content permissions (also didn't auto reload my installed plugins list on WPMU Installer Plugin dashboard). I checked the wp-content/plugins folder and saw bp_group_calendar and what I assume were some correct files. . but the after "install now" it still gave me that error popup. and also, when there are no calendar events, the yellow highlighted box sort of runs off. Making me think it is other files missing. Just not all of them I am unsure.
