We marked all our new versions as 'release candidates', so if you have a problems with it just use older version it is still available from
http://tgp.russiansubmitter.com/submitter.shtml
And if you want to try out new version with new capabilities you can try it (don't forget that you can try it for free, we don't take a cent for software updates)
Many of webmasters helps us very much when they use new versions and report bugs, or their own ideas how we can improve software.
I don't see any reason to stop doing that, because it's the only way to make great, most powerful and also cheapiest program. If we'll hire hundreds of betatesters it will raise the price.
Anyway sorry for this problem. Final release of new version is almost finished.
