Hi everyone

I've been using bitcoin for a year and a bit now, and never had any problems with it until now.
I'm using the same wallet I've used the entire time, and only recently has this problem arisen.

I'm using MulbitBit 0.5.18, as it was what I was first taught to use and as I said I've never had any problems with it, so I saw no reason to change platform.

I tried to sell some bitcoin today to Bogla, and as usual they wait for a confirm before paying which is fine.

However, it's been 9 hours and there is no confirm yet and yes I've dealt with bitcoin I know it takes a while sometimes but I'm worried as another payment I sent on the 23rd has also not confirmed.

So basically what I need help with is, how can I get my bitcoin out of this wallet and into PayPal, or another wallet that actually works 100% of the time.

Thank you for your time.
