I too got caught out with their upgrade "strategy" after purchasing the MacHeist bundle earlier this year - I too gat a very annoying shock to see that Speed Download 4 that was purchased just a few weeks ago became trial software again with out warning when applying the auto update feature in SDL4 - But it looks like a lot of humble pie is being eaten over at YazSoft. Even though they say it’s not their fault and blame MacHeist and say support for version 5 was never mentioned - They have acknowledged that it’s omission was not all MacHeists fault and should have been made clearer by YazSoft at the out set - And the auto upgrade to a trial of version 5.0 thus disabling the paid for version 4 was entirely their mistake - So they have made good by offering version 5 for $15.00 US although it took me 3 days to find the page on the YazSoft site with their apology and the instructions on howe to redeem the ver 5 upgrade for $15.00 - Not a completely satisfactory outcome but to me acceptable - It appears that a rather large amount of heat was generated over the issue and they decided to "wear the cost" - The apology is quite a good read and I have to give kudos to them for biting the pillow! - Version 5 is an improvement I guess but it still contains annoying bugs that version 4 has like reveal in finder still doesn’t work and for a while down loads were stuck in .a speed download pkg with file having to be revealed in the Finder via show package contents - Never the less it’s is 10 times faster than safari and works with all common browsers - The appology page with down load/upgrade instructions can be found here - http://www.yazsoft.com/content/mh.html
