bbPress – ForumTopic page – 404 error

We have moved our WordPress website to a new host and have lost all Topic links in our bbPress Forum Subjects. WP- 3.7, bbPress 2.5, bbPress Admin Bar 1.71, 0.3 bbPress Email
Theme: Twenty Thirteen
Other Plug-ins running:
qTranslate
NextGen
s2Member
EmailUsers
WPApproveUser
JetPack
Ajax Calendar

In the Dashboard we can see all the Forums and subjects and topics correctly. The webiste displays the Forum Topic correctly but clicking on the link creates a 404 error , page not found. We have created a new Forum subject and child Topic as a test. On the site the test Subject/Topic is visible, but again, clicking on the Topic only gives the 404 error once again.
We have run the bbPress Repair Forum tool with no success. We are not confident if we run “Reset Forums” the plugin will be functioning once after we lose all current our posts.
How can we correct the database link to our Forum Topics so the pages can be found and we avoid the 404 error? Also, how can we be certain a complete clean re-install bbPress, from scratch, will correct the current website database error? Thank you for your help.
