General Error Corrupt PreferencesLookup file

Context: You cannot launch memoQ. Upon start-up the software crashes and you are confronted with a general error.

memoQ Version: Any

Description: When the general error message appears, click on “More” in order to know better what it relates to. If the very last line of the call stack happens to be:

"Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationReaderLookupSettings.Read7_LookupSettings("

or

"Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationMQReaderLayoutSettings.Read4_LayoutSettings()"

Then your preferences-lookup.xml file is corrupt and need to be deleted so that memoQ can generate a new copy.

Fix: In order to find the preferences-lookup.xml file you must navigate to:

C:\Documents and Settings\your_user_name\Application Data\MemoQ for Windows XP users,

or:

C:\Users\your_user_name\AppData\Roaming\MemoQ for Vista and Windows 7 users.

Once you have found the file, delete it.

Comment: You may need to enable the visibility of hidden folders to find the AppData folder under windows Vista and 7.
