No, but if you don't know what this is, this BETA version is definitly not for you!
If you don't know what to do you will destroy your glest installation!
I you want to try it:
- copy your whole glest installation to something like glest_beta for example.
- remove the scenarios folder from this copied installation
- unpack all files from the patch into this new directory ( not in original glests one!!! )
What I think is showing up after your "installation" are the files you have to extract to your (copied)glest installation.
