Xavier, mon ami, would you consider it rude to make it known to a company that the $300 piece of software they sold to you is unusable? On the contary, if you release software that is, in essence, not ready for public release, then you must also accept the reactions of those unfortunate enough to purchase and try to use it.
That said, I think many of us realize that complex software such as MMV is bound to have some problems in early versions, but of course we expect that you would provide updates. It is obvious that you are under a lot of pressure, but please don't start lashing out at the users, who have trusted you and supported you with their purchases.
If I might suggest, please label the updates with unique numbers on your website. It does no good to have version 1.22 appear as the earlier 1.20. How are we to know that it is indeed an update?
From your statement that 1.22 was available on Dec 4, I can tell you that I, for one, am still having the same problems. I have tried to completely remove MMV, including all registry keys, and reinstalling 1.22 but I still have the same behavior... complete lock-up of my computer (HP Pavilion P3 1GHz, 512 MB RAM, XP-Pro).
I can except having to wait while you diagnose this and find a proper fix, but perhaps you could post a status update to the forum here so we at least know what progress is being made. Having to troll through numerous posts to try to get answers is not effective communications with your customers.
If I can be of any help in this diagnostic process, let me know. I can only try things in the evenings, but I will be more that willing to lend a hand trying updates when they are ready.
A plus tard,
Simon
