Great but needs a fix

Mostly this is great - paid to upgrade to yearly today. I did three stars because of occasional bugs that are a little annoying but easy enough to work around.

(For Support Desk)
When I paid for the subscription today it erased all my data in the app on my phone. Additionally it wont sync between the two platforms I use. I know they are both signed in to the same account because my Facebook avatar shows on each. Can you help me fix this? Sorry to bring this up here, but I need help and when I wrote to easyten.ru it wouldnt send, and each time I open the settings panel on the app (both in iPhone and iPad) it crashes. Thanks.
