I believe the software can become buggy if you change modules often. Restart the software and go directly to the module you need and don't back out of it. IE don't switch from ABS module to DTC modules or whatever. It's been a year since I used it so I don't remember all the module names.
Also do not emulate windows. The USB interface is significantly affected by emulation layers like virtual box, VMware and xen. Use windows as a host OS and run the software in compatibility mode for either win7 or winxp for best results.
