You should give a try with version 4.21.2

Clear any of the Frostwire folders under /root/ and /opt/ before you start. (You will see two folders related to Frostwire under /root/ and you should delete both of them.

If you encounter a problem deleting one of the root folders start deleting from the inner folder following the tree structure.

After deleting the locked folder you may encounter a network connection problem, if that occurs restart your router.

I have tried versions 4.21.2, 4.21.5 and the latest version 4.21.8.

4.21.2 is the only version that worked for me. It takes about a minute (or more) to load up, but once it's done it works really fast & flawless.

You can dowload the old version from :
