Preview button needs modifying.

I’m in need of assistance from fellow wordpressers. A week ago I bought a theme that required me to set my front page to a static page called ‘blog’ where all my blog posts would show up. In order to browse the posts on my website the regular reader would have to go from http://keepinspiring.me to http://keepinspiring.me/blog/

The thing is that only the browsing of posts has changed and my permalinks remain the same. The homepage redirects to the /blog/ page to make it easier for a reader to browse through posts. This, however, creates a problem for me when I try to preview a post. I’m not able to preview a post because each time I try to preview the post it redirects to /blog/?=previewname .

I’m wondering if there’s any way around this and/or to change my URL for the ‘preview’ button. Perhaps there’s some code I can put in my htaccess that will stop previews from redirecting?

Any sort of help would be appreciated.
