So, Foobar doesn't crash anymore?
If you have the TouchRemote setup in Foobar, you have to download the remote app to iPad/iPhone/iPod - not the laptop music server.
Set up the Virtual Hotspot on the laptop.
Then, on your iDevice, find the laptop-created hotspot and link to it.[Settings] - [Wi Fi] - [Choose a Network]
Once that is done, fire up Foobar on the laptop, then in [FIle] - [Preferences] - [Media Library] - [TouchRemote DACP Server] you need to click the button [Add a New Device] - a menu will pop up asking for a 4 digit number.
On the iDevice, fire up the Remote app, and then [Add an iTunes Library]. It will give you a 4-digit number, which you enter on the laptop, and it should work.
Sorry, but I'm working off (my aged bad) memory as I don't have my iPad nor my laptop server - they are both packed away and somewhere between the Venetian in Las Vegas and my office.
