Sorry that you are experiencing difficulties with your installation. Generally, installing SSTU should not cause issues with other mods, unless something was installed incorrectly (or there are major new mod conflicts that I've never seen).

Could you upload a copy of your KSP.log file? You can drag+drop it into the reply box to auto-upload. That log should contain information regarding what went wrong, where, and sometimes even why.
