Ok, check it out. We were using the 4.1.8 driver. Some of the boards were USB and others serial. We were playing around with the manual/auto detect. We knew no settings were needed for USB, so we were trying to figure out what the deal was.
Then, it kinda hit us. We downloaded the latest driver on the site, 4.1.12. we removed the old driver, installed the new and presto, the watermark was gone.
....now stay with me, this will kill ya. We figured out that there must have been a programming loop in the old driver. And when you had a USB or vice versa with serial connected, the driver still looked for the other type of connection. There wasn't anything to tell it to shut down the opposite driver. And so when you ran active studio, it recieved the message that the hardware wasn't detected (in this case, the serial driver wasn't dectcting a serial connection, but we were connnected USB). The driver loads both USB and serial and doesn't give you a choice , but that seems to be the answer to alot of the problems we've been having.
......a programming loop..........no notification...........
