To get it to sync try the following steps.

1. Go to your tigercoin.exe directory.
2. Create a shortcut of tigercoin-qt.exe
3. Go to properties.
3. Change target to tigercoin-qt.exe -reindex -par1
4. Run Tigercoin though that shortcut (It will start the blockchain from the start again, it should take some time)
5. Delete that shortcut (if you reuse it it will re-index the blockchain which takes lots of time)

Tell me if it worked!
