Ok I'm running a new install (old updated db) and I have newsletters only mod.. I now face this weird error (I guess it is a error) after I press send

Please wait .. sending emails ..

Please do not interrupt this process! [email protected]k0@C; c=%Mӵl6ul?~wm`+I&KhGr-y ozqbY;NĤ4HYeUn 9b 4RC`K{5WY† ! T#f8D="@�VC I_gI{+aaSB߅$Bi i."S!?j~ayF*ĖJO] lAV\v  SAmK&$pZ*PX;;8]^{6I^' a C;}%nOm.uc- Bqr;ȵz� Q7CQ$~{Wq=G.Xp##cѫ%4Z:,4Ʉ0%O8meL;ezK ! $NDދ0q25<ʲ7O##6xJaEt.ChC 7����9}3F��

I haven't tested with all subscribtions yet (couple thousand I guess) only with test group.. It displays only the first email image and afterwards its all china.. BUT it seems to send emails to the whole test group which is about 5 emails but it still gets stuck loading forever and now I don't now will the emails ever get delivered or not.. Any ideas how to fix it?

many thanks as always
