I too have issues opening the wallet now, it crashed after I tried sending an amount to Cryptopia, some error about exceeding the limit, and since then I can't open it anymore. Suggestions are welcome.
curiousity prevails upon me to ask,
are they showing as pending at cryptopia?
even if they are, as long as they're not confirmed it should be still possible to send them in smaller batches,
double spending is real

shame there isn't a working explorer as well :p
