Elements 2018 trial

On changing my camera Elements 10 would not load my RAW files so I had to upgrade to Elements 14. I then found that 14 did not work with my Wacom tablet so had to switch between 10 and 14 to do any editing. I have read that Elements 2018 was now compatible with my tablet and downloaded the trial version. I tried a simple edit and was informed of a memory issue and how to fix it by changing a preference setting. On trying this an error message came up about an integer range and the program locked up. On the forum it said that it was a known fault (why has Adobe not addressed this) and a register change had to be done. I did this but the error still occurs.

If adobe wants me to upgrade then this is not the way it is done. I am so glad that I did not purchase the software first as at present it would be a waste of money.

Has anybody been able to put a support ticket direct to Adobe without being continually looped back to the forum?
