On that last post from x10 pro, they state they do not have a 64 bit driver for their VA11A, and they do not see any updates on their time table to even develop a driver. This to me says it all. They have no plans to upgrade their driver, or keep up with the latest operating systems that are rapidly being sold by the big manufactures. Their perfectly content to just stay where they are and not improve. I will not buy from X10 in the future, because of this attitude. If you are thinking of upgrading your Windows XP to 64 bit, and you want to use X10 DONT upgrade, or nothing they sell will work on your system. My advice: purchase your equipment, and software from a more modern upbeat company, that strives to keep up, and inprove on their product line. X10 seems to be only be interested in getting their software they already released with tons of bugs to work properly. Here's a good idea: Don't use your customer base as guinea pigs to test your products and software, then have the customers work out the problems themselves. More money is needed in your R&D department, and engineering. If you look at your Forums you will find customers answering questions, more than actual X10 employees. What a shame!!!!
