I'm new to PTE and I think its great! Just one problem, I'm trying to add a wma music file to my show and it hangs the system (Pentium 4, 512Mb RAM). The file was downloaded from a legitimate service and fee paid but it probably has a music rights license attached. Would this prevent it from running within PTE? Is there a solution? Apreciate any help. Thanks in advance.
