My subscription options are suddenly gone!

[zero_doshomik]

I have noticed to get subscriptions for my all gigs(8).

i have set for two gigs, and thinking ofr other how to add it.

But suddenely i have found that there is no subscription option after a week later.

And, i can't delete or modify those two gigs with subscription i have set.

Is this a game! 

What should i do then!
