Problem purchasing TP via paypal

[amtoru]

Hello. I'm having some problems buying TPs via paypal.

That's what i do:

open store
click on my currently-available TPs (too few!)
select one of options (8850 tps in my case)
select paypal
click 'pay now'

in paypal: click enter, where i enter my paypal login & password
it says working..

after that i'm trying to click button 'pay now' - and nothing happens. Same if I click cancel button.
Actually, if I wait a bit and close browser windows in-game - client crashes.

Edit: I solved it by paying with mastercard directly, that worked. Paypal option did not.
