I resolved an issue of not being able to access all of MacProVideo's website. Certain parts of site pages were not functioning when I clicked on them. An example was when I clicked on the home page's "Browse by Application button, no drop down box appeared like it was supposed to. There were similar issues on other pages. The solution for me: Internet Explorer has 32 and 64 bit versions. I was using the 64 bit version, but reverted back to the default 32 bit, after reading that not all websites are able to function properly using Internet Explorer 64 bit. I get full functionality now.
