Original description

NOTE:

Due to ongoing bandwidth hustle,

there are no sessions for dowload available currently.

It seems the company isn't willing to provide storage and

bandwidth for hosting the LGI videos anymore.

I'm sorry that such relatively simple and sensible things are torpedoed by various parties.

Since I've rescued the first six sessions I might be able to provide these for the community

in case someone has enough cloud storage where I could upload the zip archives.

In the mean time i'm going to setup a small server at home for hosting the sessions.

Or try to contact the company CanControls in Aachen/Germany.
