Divayth Fyr won't give me the potion

[Gornak Matube]

Hey there,
Can anyone help? I have the boots that Fyr wants and have not hurt any one in his stronghold, but when I talk to him about getting the potion to cure my corpus he keeps telling me to retrieve the boots. I have him at 100% persuaison and he still wants be to get what I already have in my inventory.
From reading the forums it seams like no one else has had this problem. Please help..............cheers.

After 284 different trys, it turns out that the boots I was currently wearing (I had aquired them in an early plundering of some ruin) were the exact same as the ones tht Fyr wanted. This was confusing the game, so on a whim I took mine off and when I spoke to him the dialog went as it should. On the off chance that someone is on the same situation, I hope this helps.
