Is your personal name entered exactly the same on your Paypal account as on your Fusion Cash account? When I changed me method of payment from checks to paypal, I had no issues until the time when Fusion Cash was no longer allowing any differences in the name on the account.
My last name has an accent mark at the very end. That is how I registered with Fusion Cash. On my Paypal account, I didn't use the accent. That difference meant that my account was not verified. I had to change my Fusion Cash account to match exactly what is on my Paypal account - problem solved.
I have no idea if this is your issue or not but I hope the information is useful.
