One thing I noticed is that the wallet details say it is "watch only." I created a new wallet and the wallet details info is much newer. Might be because I've had the original wallet for a long time?
So this is why you can't access the funds in the wallet, you need the seeds/privkeys to access the funds and I hope you have seeds.
Just go and create a new wallet then import the wallet using seeds which will let you access the funds and move where you want to. But this contradicts what you said in the first post. you have been using the wallet for over 1 year and now only you have issues wth spending the funds or have you just used this wallet only to receive it until now?
