WPMU DEV Plugin failing to install

Hi,

I experienced two problems with installation using the WPMU DEV plugin:

1) I tried repeatedly installing the FrameMarket theme, and it did say installed but the theme was not there either through the theme lists under admin or physically in the theme directory

I ended up downloading and installing it manually.

2) I have just tried installing MarketPress. This time I am getting an error:

Downloading install package from https://premium.wpmudev.org/wdp-un.php?action=install&key=XXXXXXXXXXXXXXXXXXX&pid=144…

Download failed. error:0D0C50A1:asn1 encoding routines:ASN1_item_verify:unknown message digest algorithm

I am using WordPress 4.1, WPMU DEV Dashboard v3.4.9, Multisite configuration

I have NOT installed anything except the FrameMarket theme, which I did manually.

How do I fix this?

Tino
