CTASIO error popup message on startup of powersdr v2.7.2 when VAC enabled

Error message box at startup CTASIO. PowerSDR v2.7.2, when I enable a VAC with standard defaults I get this message on startup the error box says "there are no creative audio products ...". The VAC works and I get audio routed to the PC's audio out. I am running Vista with all the updates. Clicking ok in the error block allows proper operation but it doesn't happen on other systems and it is a pain in the ****.

    Windows only allows one ASIO audio driver to be loaded at one time. Looks like at one time you had a Creative Audio sound card with an ASIO diver loaded and now it is complaining. This happens if the CA was not fully unloaded. Try this: Go to C:windowssystem32 Look for ctasio.dll rename it to ctasio.dll.old Restart windows

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
