FTB Monster 1.1.1 missing microblocks


Hello, I just freshly installed FTB Monster 1.1.1 and updated my Server to the same version using the providers service.

But when I try connecting, I only get:

Disconnected by Server

The following microblocks are not installed on this client: tile.pearlBrick, tile.pearlBrick_1, tile.pearlBrick_2, tile.pearlBrick_3, tile.pearlBrick_4, tile.pearlBrick_5, tile.pearlBrick_6, tile.pearlBrick_7, tile.pearlBrick_8, tile.pearlBrick_9, tile.pearlBrick_10, tile.pearlBrick_11

I already tried activating all mods possible in the FTB Launcher, but that didn't help. I haven't tried Force Update yet, but since it was just freshly installed and didn't work from the start, I don't expect that to help.

Any advice would be greatly appreciated :)
