Answer 1

I will check for the meta data.. as to hows this adobes fault....first let me ask do you work for or get paid for by adobe?  If the answer is no, which i presume it is...then that answers it... how is it , or better yet why is it a billion dollar company, has or offers no support, no phone number, no email nothing...but depend on third party people who may or may not know or give the correct info to help, and do this free, all the while adobe makes $$$ and runs smaller companies that may have actually better products by getting or buying off reviews etc..that only rave, but never mention issues...the issue im having has been reported by adobe users since version 1, yet has not been addressed or even mentioned...why shouldusers get little true support from adobe, get a product that has un addressed issues is messed up...it would be like ford making newer vehicles say a f150, advertising all the bells and whistles , but knowing since their 2008 model  that if you go over 70 mph for more than 100 miles the engine will just shut off, then have know way to contact them to solve the problem...had no mechanics to fix it...no warranty...that would be insane...but yet companies like adobe and microsoft do this all the time, but since its notlife threatening as driving a truck would be somehow we accept it as ok....yet it sickens me the hardearned money spent on their products, its an investment,  like whether or not to go canon or nikon..your investing in the company its not easy to switch once you make that intial choice...  adobe and microsoft continously advertise all the so called (al beit meaningless) upgrades or improvents which are more fluff than  worth while improvent, but the way they present them you feel you need them...if they went back to the true ethics of buisness and american pride they would focus moe money and attention to customer service,  and truly improving the product rather than how to sell more...but then they know like my camera example once you choose your theirs...sad...i had an adobe salesman out right lie to me and misrepresented a product, as i was having an issue getting sound to work in creating a video of my granddaughters birth...i was using an older version, told him all the info , he said if i upgraded i would have no trouble, so i did...the sound still didnt work . Then they suggested another program to convert the files more money down...the other company also makes video editing programs, once that work...and cost less...but i am all tied up in adobe spending hundreds all ready...sad ...very sad...now that ive had some issues and have gone back and done more researching i see all tge issues, many go back 10 plus years and have yet to be addressed...yet many otherless known third party companies had similar issues, corrected them , are cheaper, have support teams but arent pushed in every photo magazine etc...and arent known where giants like Adobe that dont address there issues have or offer no Adobe paid support, yet through their money and muscle to dominate magazines, and web, by controlling how things are precieved....sad in deed...the more i learn, and experience the sadder things are....but enough complaining sadily im invested in adobe for now till i get rich,  just want the crap to work...so i can get my cherished pictures , once in a lifetime pics of my granddaughter  back...to bad people have to place faith in a company and risk loosing all the pictures that mean something to them,and realize the comoany only truly cares about $$$...sad
