I use IE7 browser and Win XP. I have this problem always I try to open lessons.
When did this error start occurring? It may have to do with the fact that some of the features on LingQ are not completely compatible with older browsers like IE7. I suggest you upgrade to IE8 or IE9 if possible, or switch to another browser such as Firefox or Chrome. This will ensure greater compatibility with LingQ.
Problems started before about 1 month ago. Before one month all was ok with the same browser IE7.
