Make sure you remove any spaces in the URL that may have gotten in during copying.

The most often the difference of debug and release version of executables is that at debug the data fields are initialized automatically and at release are not. Check do you read some variables without initializing them before. Also check the lengths of variables. Might be you overrun it, but at debug it hidden as the program
includes special additional information etc. Can be problems with synchronization. In debug the program run more slow.
