How to safely re-install Jamroom with out loosing any data

Hello All.
After installing Jamroom 6.1.5 and updating all the modules and skin, I noticed that I was not able to change the the quotas. When I tried to change from artist to member the system just hang.
So, I manually removed Jamroom 6.1.5 and the modules. After running running integrity check, it hanged.
I tried running the repair.php and did not help I got a lot of errors that I can recall since it was a late night.
Now the Market place Module is not working. I can not update update jamroom, or re-install any modules from the market place. When ever I try to do that, the page gets redirected and I get the below error.
https://www.sitename.com/marketplace/undefined, the page your requested was not found.

Hopefully manually re-installing jamroom will will resolve the problem.
If you could please point to the docs of manually re-installing jamroom with out loosing any data will be great.

One more thing, when I try to run integrety check the system hangs on "repairing table: jr_jraction_hash"

You shouldn't have removed any of the modules 'by hand'. There are tools in the marketplace to revert modules to older versions. I'm guessing that now your database tables that track installed modules do not line up with what is actually there.
Your best course of action might be to get your host to revert you to the last backup made before you did this upgrade and module removal. We can then do the upgrade again and resolve any issues properly.
Hope that helps
