a point is still too much - 64bit totally unstable under Win8.1

habs not purchased here but directly from Corel.
positive: it is clear with many input formats and never seems to work mainly processor-heavy, for me but more than 30%. quite clearly and simply designed, similar to older MAGIX products
Whats da else ???? if it's because times goes, quite quickly, as I said when !!!
negative: Program is in my system almost always inactive - according to task manager and need for any action about 15 min to wake Sleeping Beauty from, even if it only is to click the video preview under win8.1 64bit. runs completely unstable. comes with longer video footage of more than 5 hours already when importing data to a halt and I was just a standard PC with I7 CPU 4770 and R9 280x GPU.
But the greatest criticism is the audacity that calls itself support. There is the only directly weeks for installation problems and only 2 !!!!! Everything else costs a whole lot schmotter for a completely unfinished proddukt. can only say stay away from something. a company that so indifferent deal with end customers, may actually like to go bankrupt like so many with the same attitude before them. with the corel draw suite no better unfortunately. Sorry Corel ***'d like better of you write *******.
