If put in your sponsor's details, you should see two application status: sponsorship application and permanent residence application.
Normally the sponsorship application status should be in process and permanent residence application should have received status.
Now, you can look at your generic application form for reference and try linking your application. This is important that failure to do that will delay your application.
You may also try to use your sponsor's details to link if yours isn't working. It will pull out the application.
If you still have problems and believe the information you entered are right, call CIC asasp!!
