Windows Media Revocation & Renewal error message when using Soundtaxi, Tunebite

[AfxTwn]

Hi, I'm new to the forum but wanted to get people's opinion's on Soundtaxi and the like. I have ST Pro and have been using it for around a year now to convert/remove DRM on my legally downloaded Napster WMA files to a more iPod-compatible format like MP3 and AAC.

I have recently upgraded my PC's OS from XP to W7 HP 64bit and have begun to experience the Windows Media Revocation & Renewal error message being displayed after converting about 25 files. I have been emailing back and forth with ST support and they say they are aware of the problem and that their developers are looking for a fix. In the meantime I have been advised to disable all programs on startup and this does fix the problem, but of course I don't want to have to do that every time. I am going to try and see if I can run ST in compatibility mode with XP and see if it behaves itself a bit more then.

Anyway, this isn't a major gripe really, the main problem I have with the software is the inability to convert multiple files at once. Whenever I try this (on my old XP OS and my current W7) my CPu-usage hits nearly 100% resulting in my tracks skipping and clipping intermitantly. I was advised by ST to reduce the settings to convert just one track at a time but this takes an absolute age to do when converting lots of albums.

I have what I consider to be a reasonably fast PC: AMD Athlon 64 X2 4600+ CPU, 4GB of RAM, good graphics card and a good external soundcard. So I cannot understand why I can't convert lots of files at once without it either crippling my PC or causing the tracks to skip upon playback. It seems to me it must be a poorly written piece of software.

So to that end, would you recommend I switch programs to something else and if so, what? I've looked at the poll results here and it seems that Tunebite
is top followed by Soundtaxi. The trouble is that I have seen elsewhere that other people have had similar R&R error messages with TB and I'm not sure if that program would allow me to convert multiple files better than ST does.

I'm not familar with Daniusoft although I have emailed them explaining my requirements/issues but so far they haven't responded to say if their software is any better.

Sorry for this huge post but I am at my wits end with ST and just want to be able to listen to my music on my iPod Touch without having to either buy every single album (which I can't possibly afford, hence the reason I subscribe to Napster's unlimited downloads service) or change my MP3 player for one that is compatible with Napster.

Thanks for any help you can give.
