The idea that the files you were uploading could have been corrupted due to not being sent in binary mode. So you should be able to overwrite all the files you previous uploaded with a fresh set, but this time transferred in binary mode.
open_basedir restriction in effect from your error message means that there is an authorization problem on your server regarding the usable paths. You should clarify this with your host.
My 2 cents: Whether an extension is in the CDB says nothing about its quality. It is more important to read the support topics for it. Better to avoid authors who do not answer support questions themselves, who do not update their stuff, and who do not fix bugs for years.
