I believe there is a missing file from my operating system. I am using asio4all with BIAB and Realband but I only have input and output on one piece of software at a time. I am getting a message from my Tascam interface that indicates I may have an issue in the OS. I tried to scan and repair windows. I received a message that there were some corrupted files but some cannot be repaired. I do not know if this would include a missing file. Everything was initially working before. I have checked for updates on both the asio4all and the Tascam and re-installed their respective software although I did not uninstall initially, but since the popup message from the Tascam indicates the OS as a possible issue I assume that is where the problem lies. Any help would be appreciated.
Thanks Rich
