CSE HTML Validator

When I open an .htm file, hyperlinking works perfectly the first time -- it loads the .css file and locates the style declaration. After that first time, hyperlinking stops working for that .htm file -- clicking on any class name in the .htm file throws the error: "Unable to locate declaration for..." If I close the .htm file and then re-open it, it still throws the error. If I close Topstyle 5 completely and then re-open the .htm file, it works correctly once, then begins to throw the error again. If I open a second, different .htm file, hyperlinking works the first time, then stops working for that file.

Windows 8 Pro 64-bit
Topstyle 5.0.0.86

Can you send me those files, please?
