Somebody from GamesGrid just contacted me explaining the situation with them. What is basically happening is they are changing their servers to include some more advanced features. They began with their Windows poker client, and are now working on their Mac poker client. The feature that is complicating things seems to be a drag and drop feature, which apparently plays an important role in the new software.
I asked, but there is currently no timeline in which the GamesGrid update is expected to be finished. Hopefully there will be a huge improvement when GamesGrid is finished with this update. There were very few people that were fans of their traditional Mac poker software. Perhaps GamesGrid will come out with a Linux poker game sometime soon?
